Calculate the molarity of the solution formed when 0.72 moles of CaBr2 is dissolved in 1.50 L water.
xxTIMURxx [149]

Answer:

The molarity of the formed CaBr2 solution is 0.48 M

Explanation:

Step 1: Data given

Number of moles CaBr2 = 0.72 moles

Volume of water = 1.50 L

Step 2: Calculate the molarity of the solution

Molarity of CaBr2 solution = moles CaBr2 / volume water

Molarity of CaBr2 solution = 0.72 moles / 1.50 L

Molarity of CaBr2 solution = 0.48 mol / = 0.48 M

The molarity of the formed CaBr2 solution is 0.48 M

Tanya [424]

Answer:

2.98 g CO2

Explanation:

1. Balance the chemical equation

1 Fe2O3 + 3CO ->  2Fe + 3CO2

2. Use periodic table to find mass from each CO2 and Fe2O3  

3. Calculate

3.60 g Fe2O3 x \frac{1 mol Fe2O3}{159.69 g Fe2O3}x\frac{3 mol CO2}{1 mol Fe2O3} x\frac{44.01 g CO2}{1 mol CO2} =  2.98 g CO2
