You must react 5.3 g H_2 to produce 47 g H_2O.
<em>Step 1</em>. Calculate the <em>moles of H_2O</em>
Moles of H_2O = 47 g H_2O × (1 mol H_2O/18.02 g H_2O) =2.61 mol H_2O
<em>Step 2</em>. Calculate the <em>moles of H_2
</em>
Moles of H_2 = 2.61 mol H_2O × (2mol H_2/2 mol H_2O) = 2.61 mol H_2
<em>Step 3</em>. Calculate the <em>mass of H_2</em>
Mass of H_2 = 2.61 mol H_2 × (2.016 g H_2/1 mol H_2) = 5.3 g H_2
c. 0.05843 would be the correct answer.
This is because significant figures are measured by starting from the first non-zero digit, and the first non-zero digit in option c. is 5, and it ends at 3. If you count all the figures from 5 through 3, you'll find that there's 4 figures in total (5, 8, 4, 3).
