(C) To find the substance with the highest weight, we calculate the mass of each option using the formula: $	ext{Mass} = 	ext{Number of moles} 	imes 	ext{Molar mass}$.$A$. $0.2$ mole of sucrose $(C_{12}H_{22}O_{11})$:$	ext{Molar mass} = (12 	imes 12) + (22 	imes 1) + (11 	imes 16) = 144 + 22 + 176 = 342 	ext{ g/mol}$.$	ext{Mass} = 0.2 	imes 342 = 68.4 	ext{ g}$.$B$. $2$ moles of $CO_2$:$	ext{Molar mass} = 12 + (2 	imes 16) = 44 	ext{ g/mol}$.$	ext{Mass} = 2 	imes 44 = 88 	ext{ g}$.$C$. $2$ moles of $CaCO_3$:$	ext{Molar mass} = 40 + 12 + (3 	imes 16) = 100 	ext{ g/mol}$.$	ext{Mass} = 2 	imes 100 = 200 	ext{ g}$.$D$. $10$ moles of $H_2O$:$	ext{Molar mass} = (2 	imes 1) + 16 = 18 	ext{ g/mol}$.$	ext{Mass} = 10 	imes 18 = 180 	ext{ g}$.Comparing the masses: $68.4 	ext{ g} Thus, $2$ moles of $CaCO_3$ weigh the highest.
