Answer:
344.21 g/mol
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
Cr₂(SO₃)₃
<u>Step 2: Identify</u>
Molar Mass of Cr - 52.00 g/mol
Molar Mass of S - 32.07 g/mol
Molar Mass of O - 16.00 g/mol
<u>Step 3: Find</u>
Molar Mass of Cr₂(SO₃)₃ - 2(52.00) + 3(32.07) + 9(16.00) = 344.21 g/mol
Answer:
When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapor. Most of the matter in the candle ends up as these two gases.
