Answer:

12.4g of water has 0.689 moles of water.

Explanation:

Molar weight of [tex]H_{2}O[/tex] = 16 + 2 = 18g

One mole of [tex]H_{2}O[/tex] weighs 18g.

[tex]18g\longrightarrow1\:mole\:of\:H_{2}O\\12.4g\longrightarrow\frac{12.4}{18}=0.689\:moles\:of\:H_{2}O[/tex]

Hence, 12.4g of water has 0.689 moles of water.
