Answer:
Step-by-step explanation:
From the reaction:
2 moles of Na produce 1 mole of H₂
Converting 3.10 g of Na into moles:
Moles = mass / molar mass
= 3.10 / 23
= 0.135 mol
From the reaction:
2 Na = 1 H₂
1 Na = 1/2 H₂
1 Na = 0.5 H₂
1 mol of Na = 0.5 mol of H₂
0.135 mol of Na = 0.5 × 0.135 mol of H₂
0.135 mol of Na = 0.067 mol of H₂
So, 0.135 mol of Na (3.10 g) produce 0.067 mol of H₂
Convert 0.067 mol of H₂ into L:
= mol × molar value
[molar value = 22.4 L/mol]
= 0.067 × 22.4
= 1.51 L
