Answer 2

Given :

• mass of calcium hydroxide = 37 g

To find :

• Moles of calcium hydroxide.

Formula used :

$n = \dfrac{given \: mass}{molar \: mass}$

where n is number of moles.

Solution :

Molar mass of calcium hydroxide = 40+ (2×16)+(2×1)

⟹ 40+ (2×16)+(2×1)

⟹ 40+ 32+2

⟹ 74 u

Now we will find number of moles :-

$n = \dfrac{given \: mass}{molar \: mass}$

Now put :-

• given mass = 37

• molar mass = 74

$\implies \: n = \dfrac{37}{74}$

$\implies \: n = \dfrac{1}{2}$

$\implies \: n = 0.5 \: mol$

Answer :

Number of moles of calcium hydroxide = 0.5 moles.
