How many grams of hcl would be required to make 0.3 l of a 12.0 m solution?
a.25 g
b.146 g
c.131 g
d.40 g

The mass of HCl is 131 grams (option C)

Explanation:

Step 1: Data given

Volume of solution = 0.3L

Molarity = 12.0 M

Molar mass of HCl = 36.46 g/mol

Step 2: Calculate moles HCl

Moles HCl = molarity * volume

Moles HCl = 12.0 M * 0.3L

Moles HCl = 3.6 moles

Step 3: Calculate mass of HCl

Mass HCl =moles HCl * molar mass HCl

Mass HCl = 3.6 moles * 36.46 g/mol

Mass HCl = 131.3 grams ≈ 131 grams

The mass of HCl is 131 grams (option C)

sure what is it? ^w^

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
