Answer:
0.50 M
Explanation:
Given data
- Mass of sodium sulfate (solute): 7.1 g
- Volume of solution: 100 mL
Step 1: Calculate the moles of the solute
The molar mass of sodium sulfate is 142.04 g/mol. The moles corresponding to 7.1 grams of sodium sulfate are:
![7.1g \times \frac{1mol}{142.02g} = 0.050mol](https://tex.z-dn.net/?f=7.1g%20%5Ctimes%20%5Cfrac%7B1mol%7D%7B142.02g%7D%20%3D%200.050mol)
Step 2: Convert the volume of solution to liters
We will use the relation 1 L = 1000 mL.
![100mL \times \frac{1L}{1000mL} =0.100L](https://tex.z-dn.net/?f=100mL%20%5Ctimes%20%5Cfrac%7B1L%7D%7B1000mL%7D%20%3D0.100L)
Step 3: Calculate the molarity of the solution
![M = \frac{moles\ of\ solute }{liters\ of\ solution} = \frac{0.050mol}{0.100L} =0.50 M](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7Bmoles%5C%20of%5C%20solute%20%7D%7Bliters%5C%20of%5C%20solution%7D%20%3D%20%5Cfrac%7B0.050mol%7D%7B0.100L%7D%20%3D0.50%20M)
This are letters of the alphabet some are periods and some are commas also they do not form any words or meaning
hope this helped ;)
