What is the total mass of 2.0 moles of diatomic hydrogen?
Answer (3)
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
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 = molar mass ma ss
2.0 mol = 2.0 g / m o l ma ss
mass = 1 g
therefore, we can conclude that** total mass of 2.0 moles of diatomic hydrogen is 1 g.** ;
The total mass of 2.0 moles of diatomic hydrogen (H₂) is calculated using its molar mass of 2.02 g/mol. Thus, the total mass is 4.04 grams. This is found by multiplying the number of moles by the molar mass.
