The following substances are present in different containers :
(i) one gram atom of nitrogen
(ii) one mole of calcium
(iii) one atom of silver
(iv) one mole of oxygen molecules
(v) `10^(23)` atoms of carbon
(vi) one gram of iron.
The correct order of increasing masses (in grams) is/are

A

(iii) (iv)lt(i) lt(v) (b)

B

(iii) lt(vi) lt(iv) lt(ii)

C

(vi) lt(v)lt(i) lt(iv)

D

(iii) lt(ii) lt(v) lt(iv)

Text Solution

Verified by Experts

The correct Answer is:
B, C
(i) 14 g, (ii) 40 g
(iii) `108/(6.022 xx 10^(23)) = 1.79 xx 10^(-22)`g
(iv) 32 g, (v) 1.99 g, (vi) 1 g
Hence, the correct order of increasing masses is
(iii) `lt` (iv) `lt` (v) `lt` (i) `lt` (iv)` lt` (ii)
