The number of sulphur atoms in its 40 g is

A

`40 xx 6.023 xx 10^23`

B

`32 xx 6.023 xx 10^22`

C

`(40 xx 6 xx 10^23)/32`

D

`(32 xx 6 xx 10^23)/40`

Text Solution

Verified by Experts

The correct Answer is:
C
Number of sulphur atoms
` = ("Mass of sulphur in grams")/("Gram molecular weight")`
` = 40/32 = (40 xx 6.023 xx 10^(23))/(32)`
