Determine how many moles of HCL are contained in 44.9 mL of 8.00 M solution of HCl. Express your answer in decimal form rounded to three decimal places. Do not include units with your answer.
molesHCl=volumeLiters*Molarity
= .0449*8 moles
To determine the number of moles of HCl in the given solution, we can use the formula:
moles = (concentration) × (volume)
First, let's convert the volume from milliliters (mL) to liters (L):
44.9 mL = 44.9 ÷ 1000 L = 0.0449 L
Now we can substitute the values into the formula:
moles = (8.00 M) × (0.0449 L)
Calculating this expression:
moles = 0.3592
Rounding to three decimal places, the number of moles of HCl is 0.359.
