Question

NEED HELP WITH STOICHIOMETRY.

Lithium and oxygen react explosively to form lithium oxide. Write a balanced equation for this reaction (4Li+ 02-->Li_20 ) . Then calculate how many moles of lithium oxide will form if 1.68 mol of lithium are reacted with oxygen.

Answer 1

0.42 moles

Step-by-step explanation:

Use Stoichiometry to solve

`\frac{1.68 moles-of-Li}{} *(1 mole-of-Li2O)/(4 mole-of Li) =0.42 moles`
