Calculate molarity of water if its density is 1000 kg m3

Answer»

Hello Dear.

Here is the answer---

••••••••••••••••••••••

Given 》
Density of the Water = 1000 kg/m3

We know,
1 liter of water = 1 kg.
( Since, Density is 1000 kg/ m^3

Thus, 1000 ml of water = 1 kg.
(Since, 1 liter = 1000 ml)

Now, MASS of Water = 1 kg.
= 1000 g.

Molecular mass of the water molecules = 18 grams.

USING the formula,

No.of moles = Mass/ Molecular mass.
= 1000/18 moles.
= 55.56 moles.

For the Molarity,

Using the Formula,

Molarity =
(No. of Moles/Volume in ml) × 1000
= (55.56/1000) × 1000
= 55.56 M.

Thus, the molarity of the water is 55.56 M.

Hope it helps.

Have a GOOD DAY.
