what is the molar mass of hydrogen? remember to round to the hundredths place from the periodic table. 2.00 g/mol 4.00 g/mol 1.01 g/mol 2.02 g/mol

Answer

Explanation:

Step1: Check periodic - table value

The molar mass of a single hydrogen atom (H) from the periodic table is approximately 1.00794 g/mol. Rounding to the hundredths place gives 1.01 g/mol. In its elemental form, hydrogen is usually $H_2$. But the question asks for the molar mass of hydrogen (presumably a single - atom basis here).

Answer:

1.01 g/mol
