Answer:
Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.
Explanation:
By the reaction
H2+ 1/2 O2 → H2O
Moles of O2 = 5.2\32
⇒1 mole of O2 produce 1 mole of H2O
1 mole O2 will produce 2 mole of H2O
Therefore, 5.2\32 mole will produce [tex]{2}\times{\frac{5.2}\times{32}}[/tex]
⇒ Molecules of H2O will be
[tex]{2}\times{\frac{5.2}{32}}[/tex] = [tex]\frac{x}{{6.02}\times{10^23}}[/tex]
= 1.956×10^22 moleculesof H2O.
