Question

Calculate the molarity of each of the following solutions

0.56 mol of BaCl2 in 100.0 mL of solution

Answer 1

To calculate the molarity of a BaCl2 solution with 0.56 mol in 100.0 mL, convert the volume to liters and divide the moles of solute by this volume. The molarity is found to be 5.6 M.

Step-by-step explanation:

The question is asking to calculate the molarity of a BaCl2 solution. Molarity is defined as the number of moles of solute per liter of solution. To find the molarity, we divide the moles of solute by the volume of the solution in liters.

Given that we have 0.56 mol of BaCl2 in 100.0 mL of solution, the steps to calculate the molarity are as follows:

1. 
   
3. Convert the volume from milliliters to liters: 100.0 mL is equivalent to 0.100 liters (since 1 liter = 1000 milliliters).
4. 
   
6. Use the molarity formula: Molarity (M) = moles of solute / volume of solution in liters.
7. 
   
9. Plug in the values: Molarity (M) = 0.56 mol / 0.100 L = 5.6 M.

Therefore, the molarity of the BaCl2 solution is 5.6 M.
