Question

The mass of a molecule of hydrogen is 3.332 * 10^-27 kg. Find the mass of 1kg mol of hydrogen gas.

Answer 1

Hey there!

Given,

Mass of a molecule of Hydrogen = 3.332 * 10^-27 kg

1 kg mol of hydrogen gas will contain 6.02 * 10^26 molecules of Hydrogen.

∴ The mass of hydrogen gas =(6.02 * 10^26) * 3.332 * 10^-27

                                                = 2.0 kg

Hope It Helps YoU!

Answer 2

1/1*100 = 100 kg *6.022*10²³
