Question

Calculate the mass of
5moles of hydrogen gas. ​

Answer 1

Answer:

i hope this helped pls make me brainlest

Explanation:

Hydrogen’s molar mass is 1.008 g/mol. Hydrogen gas’s formula is H2 meaning its composed of two hydrogens therefore its molar mass is 2.016 g/mol. 5 mol H2 x 2.016g/mol = 10.08 g. How do I find molar mass

Answer 2

Answer: 10.08 gm/mole

Explanation: hydrogen molar mass = 1.008 gm/mole

             hydrogen contains of 2 atom H2 so mass of  H2 is = 2×1.008 gm/mole = 2.016gm/ mole

so 5 moles of hydrogen gas mass = 5 × 2.016gm/ mole

                                                                =10.08 gm/mole
