A) 296g
B) 300g
C) 396g
D) 400g​

Answer 1

Explanation:

Question

• 4 moles of Ca(OH)2 weigh?

Answer

First of all, let us find the molecular weight ( mass of one mole) of Ca(OH)₂

= 1 × Ca + 2 × OH

= (1 × Ca) + (2 × O) + (2 × H)

= (1 × 40) + (2 × 16) + (2 × 1)

= 40 + 32 + 2

= 74g

Mass of one mole of Ca(OH)₂ = 74g

Mass of 4 moles of Ca(OH)₂ = 4 × 74

= 296g

So, your answer is option (A)
