Fil in the blanks
a. The mass of 1 molecule of water `(H_(2) O)` is ………
b. The number of molecules in `16 g` of sulphur dioxide `(SO_(2))` are ……….
c. The weight of one mole of sodium carbonate `(Na_(2) CO_(3))` is……………..

Text Solution

Verified by Experts

`"Molecular mass of" H_(2)0 = 18 amu`
Weight of `6.02 xx 10^(23)` molecules of water= 18g
`"Weight of one"= (18)/( 6.02 xx 10^(23))= 2.99 xx 10^(23)`
