Question

Find the no of moles in 54 grams of water

Answer 1

$\huge{\mathfrak{\blue{\underline{Answer}}}}$

given mass of the water = 54gram

molar mass of water (H2o) = 18u

$moles = \frac{given \: mass}{molar \: mass} \\ moles = \frac{54gram}{18u}$

$\huge{\mathfrak{\blue{\underline{3moles\:of\:H2O}}}}$

Answer 2

Number of moles=mass/molar mass

=54g/18.0g

=3.0 mol
