Question

How many atoms are in 1.43 L of water?

Answer 1

1,43 l of water has mass 1.43 kg = 1430g

1. Find the molar mass of H2O by multiplying the molar mass of H by 2 and adding the molar mass of O
2. Divide 1430 by this (this is the number of moles)
3. Multiply this by 6.02 x 10²³ (this is the number of molecules)
4. Multiply this by 3 (this is the number of atoms)
