Answer 1

Explanation:

AT 273 K density of water is 1g/ml

so 18 ml will have 18 gm which is also molecular weight of water

Hence only one mole of water is present and we know that in one mole Na number of molecules  are present

Also one molecule of H2O contains  2 Lone pairs

So Na number of molecules will have 2* NA number of lone pairs

therefore x= 2
