Question

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 .

Answer 1

First convert mL to L

1L= 1000mL


`150 mL * (1L)/(1000mL) = 0.15L`

Next,

`0.10M = (X moles HCL)/(0.15L)`

`0.15*0.10= X moles`
X= 0.015 moles HCL
