Trisha and her lab partner filled a beaker with 150 milliliters of a 0.10 M HCl solution. How many moles of HCl are in the beaker? Remember, molarity = moles liter .
M=mol/liter
We know that we have 150ml=.15 L and .1 mol of HCl
Rearranging the molarity equation, we get
mol=M*l
mol=(.15)(.1)
=.015 mol
Answer:
Moles of HCl is 0.015.
Explanation:
Molarity of HCl = 0.10 M
Volume of HCl = 150 mL
Conversion factor for mL to L is,
\(1\ mL = 10^{-3}\ L\)
So, 150 mL = 0.15 L
Molarity is given by,
\(Molarity=\frac{Moles}{Volume\ in\ L} \\Moles = Molarity \times Volume\ in\ L\)
Substitute values in the above formula
\(Moles = 0.10 \times 0.15\\=0.015\ mol\)
Moles of HCl is 0.015.
