Question

A student makes 0.500 L of a 2.00 M solution of ammonium chloride

(NH4Cl). How many moles of NH4Cl are contained in the solution? Your
answer should be to the nearest tenth.

Answer 1

There is 1 mol of NH4Cl

Step-by-step explanation:

Molarity is a concentration measure that expresses the moles of solute (in this case NH4Cl) per liter of solution. In this case we calculate the moles contained in 0.5 L of solution by performing a simple rule of three:

We have a solution 2,0M --> We hace 2 moles of solute in 1 Liter of solution.

1 L solution-----2 moles of NH4Cl

0,5 L solution-----x= (0,5 L solutionx 2 moles of NH4Cl)/ 1 L solution

x= 1 moles of NH4Cl
