Answer: 1.63 moles
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number \(6.023\times 10^{23}\) of particles.
To calculate the moles, we use the equation:
\(\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar Mass}}=\)
Given mass = 223 g
Molar mass = 136.4
\(\text{Number of moles}=\frac{223g}{136.4g/mol}=1.63moles\)
Thus there are 1.63 moles in 223 g of the compound.
