Question 3
harina [27]

Answer: 0.118M

Explanation:

The formula for molarity is: M=\frac{mol solute}{L solution}

First, we need to find the number of moles of NaCl.

2.70gNaCl*\frac{1molNaCl}{58.44gNaCl} =0.05molNaCl

Next, we must convert millimeters to liters. We can do that by dividing the number of mL by 1000.

\frac{425mL}{1000} =0.425L

Now we have our needed data! All we need to do now is plug in our data to the molarity formula.

M=\frac{0.05mol}{0.425L} =0.118M

I hope this helps! Pls mark brainliest!! :)
