The mass of few entities are mentioned in the column II. Match the two columns and mark the correct option from the codes given below.

Options

A. p-(iii), q-(ii), r-(iv), s-(i)
B. p-(i), q-(ii), r-(iii), s-(iv)
C. p-(ii), q-(iv), r-(i), s-(iii)
D. p-(iv), q-(i), r-(ii), s-(iii)

Answer

A

Explanation

(p) 1 mole of `Na_2SO_3 = 126 g`
10 moles of `Na_2SO_3 = 126 xx 10 = 1260 g`
(q) 1 mole of Na = 23 g
1.5 moles of `Na = 23 xx 1.5 = 34.5 g`
(r) 1 mole of `NH_3 = 17 g`
`6.023 xx 10^23` molecules of `NH_3 = 17 g`
`1.5 xx 10^23` molecules of `NH_3 = 17/(6.023 xx 10^(23)) xx 1.5 xx 10^(23) g = 4.23 g`
(s) 1 mole of `CuSO_4 . 5H_2O = 249.5 g`
0.5 mole of `CuSO_4.5H_2O = 249.5 xx 0.5 g = 124.75 g`
