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