Question #0e34f

Answer 1

Taking density of water as `1g/(mL)`, the mass of 14mL water will be `14 g`

Now molar mass of water`=18g/(mol)`

So 14 g water contains `(14g)/(18g/(mol))=14/18mol` water.

`14/18mol` water will contain `14/18xx6.023xx10^23` molecules water.

As 1 molecule of water contains 2 atoms of Hydrogen , then number of hydrogen atoms in 14 mL water will be

`=14/18xx6.023xx10^23xx2=9.37xx10^23` atoms
