Answer:
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
The Volume of the solution is 448 mL. It can be calculated by using Molarity which is the ratio of the number of moles over the volume.
Given:
Molarity = 0.75 M
Mass of PbO = 75 g
To find:
Volume = ?
Molar mass of PbO = 207 + 16 = 223 g
Given mass of PbO = 75 g
Number of moles of PbO:
x = (75 * 1)/223
x = 0.336 moles of PbO
Calculation of Volume:
Given:
Molarity = 0.75 M
Molarity = moles / volume
Volume = moles / Molarity
Volume = 0.336 / 0.75
Volume = 0.448 l or 448 mL
