How many moles of NaCL are contained in .2570 L of a 37.5 mM Solution of NaCl?

moles = M x L

M = 37.6 mM/1000

1.46x10^-1

To calculate the number of moles of NaCl, you need to know the molarity of the solution and the volume of the solution.

Here are the steps to find the number of moles of NaCl:

Step 1: Convert molarity from millimolar (mM) to molar (M).
- The molarity of the solution is given as 37.5 mM. To convert mM to M, divide the value by 1000.
- 37.5 mM / 1000 = 0.0375 M

Step 2: Calculate the number of moles.
- The formula to calculate the number of moles is: moles = molarity x volume.
- In this case, the molarity is 0.0375 M and the volume is provided as 0.2570 L.
- Moles of NaCl = 0.0375 M x 0.2570 L = 0.0096275 moles

Therefore, there are approximately 0.0096 moles of NaCl in 0.2570 L of a 37.5 mM NaCl solution.
