How many sulfur atoms are present in 25.6 g of Al₂(S₂O₃)₃? A)0.393 B)6 C)3.95 * 10²² D)7.90 * 10²² E)2.37 * 10²³

Question

Quizplus · Accepted Answer

To find the number of sulfur atoms, first calculate the molar mass of Al₂(S₂O₃)₃, which is 342.17 g/mol. Then, find the moles of Al₂(S₂O₃)₃ in 25.6 g: 25.6 g / 342.17 g/mol = 0.0748 mol. Each formula unit contains 6 sulfur atoms, so multiply the moles by 6 and Avogadro's number (6.022 x 10²³) to find the number of sulfur atoms: 0.0748 mol * 6 * 6.022 x 10²³ = 2.37 x 10²³ sulfur atoms.
