What is the molarity of a solution containing 17.0g of nh3 in 2.0 L of solution?

A 0.5m

B 5.0m

C 0.05m

D 0.25m

E 2.0m

To find molarity use the following formula

molarity = moles / liters

first, we need to calculate the moles using the grams of NH₃. remember to convert grams to moles, you need the molar mass of the molecule which you can determine by adding the mass of each atom

molar mass of NH₃ = 14.0 + (3 x 1.01) = 17.03 g / mol

now, let convert grams to moles

17.0 g (1 mol / 17.03 grams) =.998 moles NH₃

now, we can plug in these values to solve for molarity

molarity = 0.998 mol / 2.0 Liters = 0.50 M (the answer is a)
