Question

Convert 652 g Sn(CO3)2 to moles of Sn(CO3)2. (mm = 238.73 g/mol)

Options:
a) 2.728
b) 5.764
c) 6.129
d) 8.625

Answer 1

To convert 652 g of Sn(CO3)2 to moles, divide the given mass by the molar mass of Sn(CO3)2 (238.73 g/mol), which equals 2.728 moles.

Step-by-step explanation:

To convert 652 g of Sn(CO3)2 to moles of Sn(CO3)2, you would use the given molar mass of Sn(CO3)2, which is 238.73 g/mol. The conversion formula from grams to moles is:

Number of moles = mass (g) / molar mass (g/mol)

Using this formula:

Number of moles = 652 g / 238.73 g/mol = 2.728 moles of Sn(CO3)2

Thus, the correct option is (a) 2.728.
