Question

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

Explanation:

Step1: Determine the formula of hydrogen gas

Hydrogen gas is \(H_2\).

Step2: Find the atomic mass of hydrogen

From the periodic table, the atomic mass of hydrogen (\(H\)) is \(1.01\space g/mol\).

Step3: Calculate the molar mass of \(H_2\)

The molar mass of \(H_2\) is \(2\times1.01\space g/mol=2.02\space g/mol\)

Answer:

C. \(2.02\space g/mol\)
