Question

one litre of water contains how much water​

Answer 1

Answer: The number of water molecules in 1 L of volume is

Explanation:

To calculate mass of a substance, we use the equation:

We are given:

Density of water = 1 g/mL

Volume of water = 1 L = 1000 mL    (Conversion factor:  1 L = 1000 mL)

Putting values in above equation, we get:

To calculate the number of moles of compound, we use the equation:

Given mass of water = 1000 g

Molar mass of water = 18 g/mol

Putting values in above equation, we get:

According to mole concept:  

1 mole of compound contains number of molecules

So, 55.55 moles of water will contain = number of molecules.

Hence, the number of water molecules in 1 L of volume is 3.345×10(25)
