Question

Calculate the number of moles of NaCl in 100.0 ml of a 0.15 M solution of NaCl.

Answer 1

Answer:

Moles = 0.775 moles of NaCl

Explanation:

Molarity

=

moles of solute

Liters of solution

First, we need to convert  

500 mL

to Liters

500 ml

⋅

1 L

1000 ml

=

.5 L

Now we can plug it into our formula

1.55M

= moles

.5

moles = 0.775 moles of NaCl
