Question

What is the number of molecules present in 1-5 mole of ammonia `(NH_(3))`?

Answer 1

1.0 mole of ammonia `(NH_(3))` contains molecules `= 6.022 xx 10^(23)`
1.5 mole of ammonia `(NH_(3))` contains molecules `=((6.022 xx 10^(23))xx(1.5 "mole"))/((1.0 mol))`
`= 9.033 xx 10^(23) ` molecules.
