Explanation:
First find the mass of 1 mole of water (Molecular mass)
[tex] H_{2} O = 2H + O [/tex]
[tex]
= 2(1) + 32 [/tex]
[tex]
= 34 \: grams
[/tex]
Hence 1 mole of water is 34 g
Compare
1 mole = 34 g
1.33 mole = x g
[tex] \frac{x}{34} = \frac{1.33}{1} [/tex]
[tex]
x = 1.33 \times 34 [/tex]
[tex]
\color{blue}{\boxed{x = 45.2}} \: \: \: \: to \: 3 \: s.f.
[/tex]
Therefore 1.33 moles of water is 45.2 grams
