Calculate the number of water molecule present in one drop of water wh

1.	Calculate the number of water molecule present in one drop of water which weights 0.18 g inplease answer me...then i will follow you.
Answer» Answer: W= 0.18 G M of H2O= 18 g (mass) ∴n = 0.18/18 = 0.01 (MOLES) 1 mole contains 6.023×10²³ molecules ∴0.01 mole contains (6.023×10²³)×0.01 = *<U>6.023×10^21 molecules* Hope this helps u.....

Answer:

W= 0.18 G

M of H2O= 18 g (mass)

∴n = 0.18/18 = 0.01 (MOLES)

1 mole contains 6.023×10²³ molecules

∴0.01 mole contains (6.023×10²³)×0.01 = <U>6.023×10^21 molecules

Hope this helps u.....
