Verified Answer :
diatomic hydrogen is written as H2 (2.02 grams H2) <------- if each hydrogen atom is 1.01 grams, then two hydrogen atoms are 2.02 grams 2.0 moles H2 X 2.02 grams H2 ------------- (divide to cancel moles) = 4.04 grams/mole H2 ÷ one mole = 4.04 grams H2
Explanation:
A diatomic molecule is defined as the molecule which contains two atoms.
For example, a \(H_{2}\) molecule has two atoms of hydrogen.
Molar mass of a \(H_{2}\) molecule is 2.0 g/mol. Therefore, calculate the mass of 2.0 moles of diatomic hydrogen as follows.
No. of moles = \(\frac{mass}{\text{molar mass}}\)
2.0 mol = \(\frac{mass}{2.0 g/mol}\)
mass = 1 g
therefore, we can conclude that total mass of 2.0 moles of diatomic hydrogen is 1 g.
