calculate the molarity of each solution.
part a ) 0.112 mol of sucrose in 658 mL of solution
part b) 0.245 mol of KNO3 in 0.875 L of solution
part c) 1.9 mol of KCl in 2.1 L of solution
a)
Molarity = number of moles of solute per liter of solution
molarity of sucrose = (0.112mol/ 658ml) × 1000ml
molarity of sucrose = 0.170M
b)
Molarity of KNO3 = ( 0.245mol/ 0.875L) × 1L
Molarity of KNO3 = 0.280M
c)
Molarity of KCl = ( 1.9 mol/2.1L ) ×1L
Molarity of KCl = 0.905M
