Question

What is the mass of 5moles of hydrogen gas

Answer 1

Answer:

The definition of a mole is a quantity of material with a mass in grams numerically the same as the atomic or molecular weight. If one mole of hydrogen is equal to 1.01 grams, then does one mole dihydrogen equal 2.02 grams. The chemical formula of hydrogen gas is H2, so its molar mass(M) is 2 gmol^-1.

Answer 2

Answer:

Here is your answer

Explanation:

The definition of a mole is a quantity of material with a mass in gas numerically the same as the atomic or molecular weight. If one mole of hydrogen is equal to 1.01 grams, then does one mole dihydrogen equal 2.02 grams. The chemical formula of hydrogen gas is H2, so its molar mass (M) is 2 gmol^-1. m=n*M=2 gram.
