How many molecules are present in 1 ml of water?
Answered by admin @
, we have molecular mass of water H2O
= 1x2 + 16 = 18 gm
Since, 1 mol water = molecular mass
in gm = 18gm.
As no. of molecules = no. of moles x
avogadro's no.
And No. of moles = given mass/
molecular mass.
Here, given mass = 1ml= 1gm
Thus, no. of moles of water in 1 ml =
1/18 mol.
And so No. of molecules in 1ml water
= no. of moles x avogadro's no. = 1/18 X 6.022 x 1023 =0.33 x
1023 molecules
So, the no. of molecules of water in
1ml of water = 3.3 x 1022
if u like plz..mark it brainliest..*-*
