Answer

0.0181 moles Explanation 1. Calculate Molar Mass of Sn(CO_{3})_{2} Tin (Sn) has a molar mass of 118.71 g/mol, Carbon (C) is 12.01 g/mol, and Oxygen (O) is 16.00 g/mol. The formula Sn(CO_{3})_{2} consists of 1 Sn, 2 C, and 6 O atoms. Thus, the molar mass is calculated as follows: \[ \text{Molar Mass} = 118.71 + 2(12.01) + 6(16.00) = 118.71 + 24.02 + 96.00 = 238.73 \, \text{g/mol} \] 2. Convert Grams to Moles Use the formula **moles = \frac{\text{mass}}{\text{molar mass}}**. Substitute the given mass and calculated molar mass: \[ \text{Moles of } Sn(CO_{3})_{2} = \frac{4.32}{238.73} = 0.0181 \, \text{moles} \]

Explanation

1. Calculate Molar Mass of $Sn(CO_{3})_{2}$<br /> Tin (Sn) has a molar mass of 118.71 g/mol, Carbon (C) is 12.01 g/mol, and Oxygen (O) is 16.00 g/mol. The formula $Sn(CO_{3})_{2}$ consists of 1 Sn, 2 C, and 6 O atoms. Thus, the molar mass is calculated as follows:<br />\[ <br />\text{Molar Mass} = 118.71 + 2(12.01) + 6(16.00) = 118.71 + 24.02 + 96.00 = 238.73 \, \text{g/mol}<br />\]<br /><br />2. Convert Grams to Moles<br /> Use the formula **moles = \frac{\text{mass}}{\text{molar mass}}**. Substitute the given mass and calculated molar mass:<br />\[ <br />\text{Moles of } Sn(CO_{3})_{2} = \frac{4.32}{238.73} = 0.0181 \, \text{moles}<br />\]
