Answer:
Mass = 14.64 g
Explanation:
Given data:
Volume of solution = 1.25 L
Molarity of Solution = 0.15 M
Mass of CaF₂ = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
We will calculate the number of moles of CaF₂ and then determine the mass by using number of moles.
0.15 M = number of moles of solute / 1.25 L
number of moles of solute = 0.15 M × 1.25 L
number of moles of solute = 0.1875 mol/L × L
number of moles of solute = 0.1875 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.1875 mol ×78.07 g/mol
Mass = 14.64 g
The Mass of CaF₂ is 14.64 g. Molarity is the ratio of number of moles over the volume of solution.
Given:
Volume of solution = 1.25 L
Molarity of Solution = 0.15 M
To find:
Mass of CaF₂ = ?
What is Molarity?
Molarity is used to describe the concentration of solution. It is given by number of moles divided by volume of solution in litres.
Molarity = number of moles of solute / L of solution
We will calculate the number of moles of CaF₂ and then determine the mass by using number of moles.
0.15 M = Number of moles of solute / 1.25 L
Number of moles of solute = 0.15 M * 1.25 L
Number of moles of solute = 0.1875 mol/L * L
Number of moles of solute = 0.1875 mol
Calculation of mass:
Mass = number of moles / molar mass
Mass = 0.1875 mol *78.07 g/mol
Mass = 14.64 g
Thus, the mass of CaF₂ is 14.64 grams.
