Find the weight of `12.046xx10^(25)` number of ammonia molecules.

Text Solution

Verified by Experts

1 gram-mole ammonia=17g of ammonia.
`therefore`Number of molecules contained in 1 gram-mole of ammonia`=6.022xx10^(23)`
Hence, `6.022xx10^(23)` molecules weigh 17g
`therefore 12.046xx10^(25)` molecules weight
`=(17xx12.046xx10^(25))/(6.022xx10^(23))=3400g=3.4kg`.
