Answer: The number of moles of [tex]MgS_2O_3[/tex] is 1.36 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]
Given mass of [tex]MgS_2O_3[/tex] = 185 g
Molar mass of [tex]MgS_2O_3[/tex] = 136.43 g/mol
Putting values in above equation, we get:
[tex]\text{Moles of }MgS_2O_3=\frac{185g}{136.43g/mol}=1.36mol[/tex]
Hence, the number of moles of [tex]MgS_2O_3[/tex] is 1.36 moles.
