------------------------------------------------ How many moles of lithium metal react to yield 5.00 mol of hydrogen gas?

\[ \text{Li(s) + H}_2\text{O(l)} \rightarrow \text{LiOH(aq) + H}_2\text{(g)} \]

A. None of the above
B. 20.0 mol
C. 2.50 mol
D. 10.0 mol
E. 5.00 mol

Answer :

According to stoichiometry and balanced chemical equation 10 moles of lithium metal react to yield 5.00 mole of hydrogen gas.

What is stoichiometry?

Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.

In the balanced chemical equation as 2 moles of lithium produce 1 mole of hydrogen.

∴for 5 moles of hydrogen to be liberated,5×2/1=10 moles of lithium are required.

Thus, 10 moles of lithium are required to react to yield 5 moles of hydrogen gas.
