Answer: The number of moles of \(MgSiO_3\) is 2.02 moles.
Explanation:
To calculate the number of moles, we use the equation:
\(\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\)
We are given:
Given mass of \(MgSiO_3\) = 203 g
Molar mass of \(MgSiO_3\) = 100.4 g/mol
Putting values in above equation, we get:
\(\text{Moles of }MgSiO_3=\frac{203g}{100.4g/mol}=2.02mol\)
Hence, the number of moles of \(MgSiO_3\) is 2.02 moles.
