6. Calculate the molarity if 35.0 grams of KBr are dissolved in 700. ml?


Answer:

To calculate molarity, divide the number of moles of solute by the volume of the solution in liters. If you don't know the number of moles of solute but you know the mass, start by finding the molar mass of the solute, which is equal to all of the molar masses of each element in the solution added together.

Explanation:

try starting with 35.0 and dived it by the volume

Answer:

About 0.4143M

I gave you extra numbers after the decimal point in case you have to round higher.

Explanation:

Molarity is the Moles per liter ratio so we need to find how many moles of KBr are in 35 grams which is about 0.29 moles.

So no (0.29)/(0.7)=0.4143

The 0.7 is from 700ml is 0.7 Liters.
