Answer:
29.22 g NaCl
Explanation:
0.5 mol NaCl x (58.44 g NaCl / 1 mol NaCl)
= 29.22 g NaCl
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
