Answer:

See explanation

Explanation:

Number of moles = given mass/molar mass

For Ca(OH)2

n= 31.82g/74g/mol= 0.43 moles

n = mass/ molar mass

Molar mass of K2SO3 = 158g/mol

mass= 3.2 × 158 = 505.6 g

1 formula unit = 6.02 × 10^23

1 mole = 6.02 × 10^23

x moles = 7.25x10^23

x = 7.25x10^23/6.02 × 10^23

x= 1.2 moles

1 mole of Cl2 occupies 22.4 L at STP

x moles of Cl2 occupies 46.6L

x = 46.6/22.4

x= 2.1 moles
