The density of liquid (mol.wt. `= 70`) is `1.2 g mL^(-1)`. If `2 mL` of liquid contains `35` drops, the number of molecules of liquid in one drop are:

The density of a pure liquid (molecular mass =80) is 1.5 gm/ml. if 4 ml of liquid contains 60 drops then the number of molecules per drops of liquid is give by : [Given N_(A)=6xx10^(23) ]

The density of a pure liquid (molecular mass = 80) is 1.5gm//ml . If 4 ml of liquiid contains 60 drops. Then the numberof molecules per drop of liquid is given by : [Given : N_(A) = 6 xx 10^(23)]

If 1 ml of water contains 20 drops. Then no. of molecules in a drop of water is

If 1 ml of water contains 20 drops. Then no. of molecules in a drop of water is

The volume of one mole of water at 277K is 18ml. One ml of water contains 20 drops. The number of molecules in one drop of water will be:
