Answer:
0.045 M
Explanation:
Given data:
Mass of NaHSO₄ = 12 g
Volume of solution = 2.00 L
Molarity of solution = ?
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
Number of moles = 12 g/ 120.06 g/mol
Number of moles = 0.09 mol
Molarity:
Molarity = 0.09 mol / 2.00L
Molarity = 0.045 mol/L
M = mol/L
Molarity = 0.045 M
