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:
Two similar atoms or different atoms
Explanation:
A molecule is made up of at least two similar atoms or different atoms.
A molecule is the smallest particle of a substance capable of independent existence.
- Monoatomic molecule is made up of one atom
- Diatomic molecule is made up of two atoms bounded together.
- Polyatomic molecule are made up of more than two molecules bounded together.
Answer:
165.5 g of CO2
Explanation:
We must first put down the balanced reaction equation:
C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H2O(g)
From the reaction equation, one mole of butane occupies 22.4 L hence we can establish the stoichiometry of the reaction thus:
22.4 L of butane created 174 g of CO2
Therefore 21.3 L of butane will create 21.3 × 174/22.4 = 165.5 g of CO2
Answer:
moles solute = 25.5 / molar mass
moles solute /0.1 Kg = molality
delta T = molality x 1.86
freezing point = 0°C - delta T
