How to Calculate the Number of Moles in a Solution
Introduction
Calculation
The formula to calculate the number of moles in a solution is n = M x V, where n is the number of moles, M is the molarity of the solution, and V is the volume of the solution in liters. To begin, we need to convert the volume of the solution from milliliters to liters. Volume = 37.5 mL = 37.5 / 1000 = 0.0375 L Next, we can use the formula n = M x V to calculate the number of moles of solute. n = 0.445 x 0.0375 n = 0.0166875 moles of KNO3 in 37.5 mL of a 0.445 M KNO3 solution.Summary
In conclusion, by knowing the molarity of the solution and the volume of the solution, you can easily calculate the number of moles of solute present. This calculation is essential for various chemistry applications and experiments. Hope I helped!How many moles of KNO3 are in 37.5 mL of 0.445 M KNO3 solution?
