How many carbon atoms are there in 25.0 grams of Al₂(CO₃)₃?

Question

Quizplus · Accepted Answer

First, calculate the molar mass of Al₂(CO₃)₃, which is 233.99 g/mol. Then, find the moles of Al₂(CO₃)₃ in 25.0 grams: 25.0 g / 233.99 g/mol = 0.1068 mol. Since each formula unit contains 3 carbon atoms, multiply the moles by 3 to get the moles of carbon atoms: 0.1068 mol x 3 = 0.3204 mol. Finally, convert moles of carbon atoms to atoms using Avogadro's number: 0.3204 mol x 6.022 x 10²³ atoms/mol = 1.93 x 10²³ atoms.
