The number of water molecules in 1 litre of water is
Answers
Answer:
1000
One mole of water has a mass of 18 grams and a volume of 18 mL (as the density of water is 1 g per cm3). It contains Avogadro's number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23. molecules......
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
