Question

What is the molar mass of hydrogen??

Answer 1

The relative atomic mass of hydrogen is 1.007.

MOLAR MASS OF AN ELEMENT = RELATIVE ATOMIC MASS * MOLAR MASS CONSTANT(1g/mol)

for HYDROGEN,

MOLAR MASS of Hydrogen = 1.007*1g/mol

MOLAR MASS of Hydrogen= 1.007 g/mol

For H2: 1.007 x 2 = 2.014 grams per mole
