Sagot :
Answer: 0.118M
Explanation:
The formula for molarity is: [tex]M=\frac{mol solute}{L solution}[/tex]
First, we need to find the number of moles of NaCl.
[tex]2.70gNaCl*\frac{1molNaCl}{58.44gNaCl} =0.05molNaCl[/tex]
Next, we must convert millimeters to liters. We can do that by dividing the number of mL by 1000.
[tex]\frac{425mL}{1000} =0.425L[/tex]
Now we have our needed data! All we need to do now is plug in our data to the molarity formula.
[tex]M=\frac{0.05mol}{0.425L} =0.118M[/tex]
I hope this helps! Pls mark brainliest!! :)
