Answer:
9.15 × 10²³ molecules of N₂O present.
Explanation:
Given data:
number of moles = 1.52 mol
molar mass of N₂O = 44.013 g/mol
number of molecules = ?
Solution:
First of all we will calculate the mass of 1.52 mol.
mass = number of moles × molar mass
mass = 1.52 × 44.013 g/mol
mass = 66.9 g
Now we will find the number of molecules by using Avogadro number,
The number 6.022×10∧23 is called Avogadro number and it is the number of atoms or molecule in one gram atom of an element or one gram molecule of a compound.
44.013 g of N₂O = one mole of N₂O= 6.02 × 10²³ molecules
For 66.9 g:
66.9 g/ 44.013 g × 6.02 × 10²³ molecules
9.15 × 10²³ molecules of N₂O present
