Quizplus · Accepted Answer

To calculate the number of moles of HCl in 75.0 mL of 2.00 M HCl, we need to use the formula:

moles = concentration (M) x volume (L)

First, we need to convert the volume from milliliters (mL) to liters (L):

75.0 mL = 75.0/1000 L = 0.075 L

Now we can plug in the values:

moles = 2.00 M x 0.075 L = 0.150 moles

Therefore, the answer is C) 0.150 moles.
