How many liters of a 0.75 M solution can be made with 75 g of lead (II) oxide

The answer to your question is 0.448 l or 448 ml

Explanation:

Data

Volume = ?

Concentration = 0.75 M

mass of PbO = 75 g

Process

1.- Calculate the molar mass of PbO

PbO = 207 + 16 = 223 g

2.- Calculate the number of moles in 75 g

                        223 g 1 mol

                          75 g  x

                              x = (75 x 1)/223

                              x = 0.336 moles of PbO

3.- Calculate the volume

Molarity = moles / volume

-Solve for volume

Volume = moles / Molarity

-Substitution

Volume = 0.336 / 0.75

-Result

Volume = 0.448 l or 448 ml
