The number of molecules of gases in each of the 3 vessels is the same.
<h3>Number of moles</h3>
The first vessel contains 2g of 
gas:
Number of molecules in 2 g = 2/2 = 1 mole
The second vessel contains 32 g of 
gas:
Number of molecules = 32/32 = 1 mole
The third vessel contains 44 g of 
gas:
Number of molecules = 44/44 = 1 mole
Thus, the 3 vessels contain the same number of moles of gases.

2.5 X 10²⁴ atoms of copper is equivalent to 266.7g of Cu.
HOW TO CALCULATE MASS:
- The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass. That is;
- mass of substance (g) = no. of moles (mol) × molar mass (g/mol)
- However, the number of moles of copper must first be calculated by dividing the number of atoms by Avogadro's number as follows:
- no. of moles of Cu = 2.5 X 10²⁴ ÷ 6.02 × 10²³
- no. of moles = 2.5/6.02 × 10²⁴-²³
- no. of moles = 0.42 × 10¹
- no. of moles = 4.2moles of copper.
- Molar mass of copper = 63.5g/mol
- Mass of copper = 4.2mol × 63.5g/mol
Therefore, 2.5 X 10²⁴ atoms of copper is equivalent to 266.7g of Cu.
