Question

Calculate the volume and mass of 0.2 mole of O3 at STP​

Answer 1

Explanation:

$\bold{(a) \: \sf{For \: Calculation \: of \: volume}} \\ \sf{Volume \: of \: 1 \: mole \: of \: O_{3} \: at \: STP = 22.4L} \\ </p><p> \sf{Volume \: of \: 0.2 \: mole \: of \: O_{3} \: at \: STP = 22.4 \times 0.2} \\ \boxed{\sf{Volume \: of \: 0.2 \: mole \: of \: O_{3} \: at \: STP = 4.48 \: litre}} \\ \\ \bold{(b) \: \sf{For \: Calculation \: of \: mass}} \\ \sf{Mass \: of \: 1 \: mole \: of \: O_{3} = 48g} \\ \sf{Mass \: of \: 0.2 \: mole \: of \: O_{3} = 48 \times 0.2gm} \\ \boxed{ \sf{Mass \: of \: 0.2 \: mole \: of \: O_{3} = 9.6g}}$

Answer 2

Explanation:

Mass of one mole of

O3 = 48 g

so,

mass of 0.2 moles = 48 × 0.2

= 9.6 g

Volume of 1 mole = 22.4 L

so,

volume of 0.2 moles

= 22.4 × 0.2

= 4.48 L
