Question

Which among the following have highest number of molecules. (SSLC 2019) *

1 point

8g H2

64g O2

28g N2


​

Answer 1

Explanation:

No. of moles = W/M = weight/(molecular weight)

(a) no. of moles = 44/44 = 1

(b)no. pf moles = 48/32 = 1.5

(c) no. of moles = 8/2 =4

(d)no. of moles = 64/64 =1

Hence, (c) have the maximum molecules

4 moles, i.e. 4×6.023×10^23 molecules
