If 10 23 hydrogen molecules strike, per second, a fixed wall of area 2 cm 2 at an angle of 45° to the normal, and rebound elastically with a speed of 10 3 m/s, then the pressure on the wall is nearly : (1) 4.70 × 10 3 N/m 2 (2) 2.35 × 10 2 N/m 2 (3) 4.70 × 10 2 N/m 2 (4) 2.35 × 10 3 N/m 2 use your notebook for your answer brainly[tex]y5 {64 {6 {14 {x { \frac{3 \sqrt{31 { {79 {4 \sqrt[42 {. Assume the sun is surrounded by a cloud of molecular hydrogen gas and that the just formed Earth orbits the sun at 1 AU in this cloud. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. In a collinear collision, a particle with an initial speed v0 strikes a stationary particle of the same mass. We know that, 1 kg mol of hydrogen gas = 6.02×10²⁶ molecules of hydrogen. Also, remember to convert Kelvin to Celsius. assume that there are 6.02x10^23 molecules in the syringe. Now, we have the mass of a single water molecule and the mass of the world´s oceans: 3.1 x 10⁻²⁶ kg ⇒ 1 water molecule. If 1023 hydrogen molecules strike, per second, a fixed wall of area 2 cm2 at an angle of 45° to the normal, and rebound elastically with a speed of 103 m/s, then the pressure on the wall is nearly :(1) 4.70 × 103 N/m2(2) 2.35 × 102 N/m2(3) 4.70 × 102 N/m2(4) 2.35 × 103 N/m2. ]{?} We know that, 1 kg mol of hydrogen gas = 6.02×10²⁶ molecules of hydrogen. The molar mass of any element or molecule is given by the sum of the atomic weights multiplied by 1 g/mol. Temperature - °C Submit Question }^{?} Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. 3 2 × 1 0 − 2 7 kg. 1.4 x 10²¹ kg ⇒ x = 1.4 x 10²¹ kg * 1 molecule/ 3.1 x 10⁻²⁶ kg Mass of the molecule of hydrogen atom is= 3.332×10⁻²⁷ kg. A list of some molar masses can be seen below. }^{2} | }^{2} }^{2} } }{?} Quite a few of you did this calculation for an O atom, rather than a molecule. This means that 1 MOLE of hydrogen atoms will weigh 1.008 grams. round the coefficient to the nearest hundredth) and calculate the mass of one oxygen atom if an oxygen molecule consists of 2 atoms. Definitions of molecular mass, molecular weight, molar mass and molar weight. }^{?} Mass of a molecule of Hydrogen = 3.332 * 10^-27 kg. The mass of 1 water molecule in Kg is: mass of H2O(kg) = 18 u * (1.7 x 10⁻²⁷ Kg/1.0 u) = 3.1 x 10⁻²⁶ kg. A molecule of hydrogen has an atomic weight of 2 g/mol. Hint: in physics, mass is measured in kg. You may need to download version 2.0 now from the Chrome Web Store. ❤​, 3)write down the differentexpressionsfor self inductanceAns​. The mass of a hydrogen molecule is 3.32 × 10–27 kg. {.7 \frac{6 \sqr ❤❤pls follow to my bestie....!! If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. }^{?} Therefore, while significantly less mass of hydrogen fuel would be required to power a vehicle for the desired range, the problem arises with the volumetric storage of such a quantity. ]{?} \times \frac{?}{?} Find the temperature at which a molecule of hydrogen has a rms speed of 500 m/s. ✌thnq bestie...!! }^{?} }^{?} \times \frac{?}{?} (1 u is equal to 1/12 the mass of one atom of carbon-12) Mass of the molecule of hydrogen atom is= 3.332×10⁻²⁷ kg. }^{2} }^{?} On a mass basis, this result is reversed, with hydrogen demonstrating its promise as a future energy carrier with an LHV of 120,000 kJ/kg vs petrol at 43,400 kJ/kg. Find the mass of 1 kg mol of hydrogen gas, please come fast in google meet code is mko-jjzz-hro​, Identify the physical quantity having dimension [M1L-3T0] That said, to find the mass of one ATOM, we need to convert from moles to atoms as follows: 1.008 grams/mole Hydrogen * (1 mole/6.022x10 23 atoms) = 1.67 x 10 -24 grams in an experiment, a chemist collected about 32 grams of oxygen molecules in a gas syringe. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. 5. \times \frac{?}{?} Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. Examples of molecular weight computations: CO2, SO2. The mass of a hydrogen molecule is 3.32 × 10^–27 kg. \times \frac{?}{?} And a few of you used half the mass of the atom, rather than twice the mass of the atom, for the mass of the molecule. • ∴ The mass of 1 kg mol of hydrogen gas
