Answer in units of mol.

Option 1. 1.365mol

Explanation:

First, we need to generate a balanced equation for the reaction. This is illustrated below:

2Li + H2O —> Li2O + H2

From the equation,

2moles of Li reacted to produced 1mole of Li2O.

Therefore, 2.73 mol of Li will react to produce = 2.73/2 = 1.365mol of Li2O.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
