60 points please help me! i will appreciate it!

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

the answer would be a
