Vlad1618 [11]

Answer:

344.21 g/mol

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table

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

How many grams of carbon dioxide are created from the complete combustion of 21.3 L of butane at STP?
Bond [772]

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

Compute the freezing point of this solution:
Softa [21]

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
