Molecular Mass of water:-

$\\ \sf\longmapsto H_2O$

$\\ \sf\longmapsto 2(1u)+16u$

$\\ \sf\longmapsto 2u+16u$

$\\ \sf\longmapsto 18u$

$\\ \sf\longmapsto 18g$

1mole of water weighs 18g

We know

$\\ \sf\longmapsto 1mol=6.023* 10^23molecules$

Mass of one molecule:-

$\\ \sf\longmapsto (18)/(6.023* 10^23)$

$\\ \sf\longmapsto 2.98* 10^24g$
