Answer:
I mean i got my own problems
Explanation:
Answer:
Gram molecular mass = 40 + (35.5)2 = 111g
Mass of 
in 1 mole = 111g
Mass of in 0.15 mole = 111 × 0.15 = 16.65 g
Answer:
5 g of H₂ are contained in the vessel
Explanation:
A typical excersise of conversion:
We determine molar mass of H₂.
This is a dyatomic molecule, as molar mass of H is 1g/mol, molar mass of H₂ will be 2g/mol.
Let's make the conversion of units:
2.5 mol . 2g/mol = 5 g
5 g of H₂ are contained in the vessel
