Answer 1

Question: What is the volume of a 1.50 M solution if it contains 55 g of ammonium chloride?

You must use the following formula M = moles/Liters

But right now you don't have moles, you have grams.

1. Use molar mass to convert g of NH₄Cl to moles.
2. molar mass from periodic table is
3. 14.01 + (1.01*4) + 35.45 = 53.5 g
4. Divide given mass by molar mass to get moles
5. 55 g * (1 mol/53.5 g) = 1.03 mol
6. Plug in values to M= mol/L and solve for L (volume)
7. 1.50 = 1.03 mol/L
8. 0.69 L (rounded to 2 sig figs)

Answer 2

First, find the molar mass of ammonium chloride (NH₄Cl) using the periodic table. This will give you a value with the units in grams per mole (g/mol). The volume of the solution is in moles per liter (mol/L). Dividing the number of grams by the molar mass gives you the number of moles. From there you can use the molarity of the solution to find the volume of the solution in liters.
