A liter of water is 1000g of water. To get the number of moles per liter of water, we divide the mass of 1L of water (1000g) by the mass of a mole of water (18g / mole). 1000 / 18 = moles.!

Answer:
Answer:
Explanation:
Desnsity of water = mass of water/volume of water
1 = mass of water/1000
Mass of water = 1000 × 1
Mass of water = 1000g
Molecular weight of water = H2O= 2×1 + 1×16 = 2+16 = 18u
Mole = given weight/molecular weight
= 1000g/18u
= 55.55mole
In 1 mole, there are 6.022 × 10²³ molecules.
Then, in 55.55 moles = 55.55 × 6.022 × 10²³
= 3.345 × 10²³
