Question

(Pls helppp!!) What is the molar mass of hydrogen if it’s atomic mass is 1.008 amu? Explain how you determined the answer.

Answer 1

The molar mass of hydrogen is 1.008 g/mol.

Step-by-step explanation:

The molar mass of hydrogen is 1.008 g/mol.

To determine the molar mass of hydrogen, we can use the atomic mass of hydrogen, which is 1.008 amu (atomic mass units).

1 amu is defined as one twelfth of the mass of a carbon-12 atom, which is 1.66 x 10^-24 grams. To convert the atomic mass of hydrogen from amu to grams, we multiply 1.008 amu by the conversion factor 1 amu = 1.66 x 10^-24 grams

1.008 amu * (1 g/1.66 x 10^-24 amu) = 1.008 g/mol

So, the molar mass of hydrogen is 1.008 g/mol.

Alternatively, we can use Avogadro's number (6.022 x 10^23) to convert the atomic mass of hydrogen from amu to g/mol

1.008 amu * (1 g/mol) / (6.022 x 10^23 amu) = 1.008 g/mol

So, the molar mass of hydrogen is 1.008 g/mol.
