What is the molarity of 3.7 moles of KBr dissolved in 2 L of water?

The molarity is : 1, 85M

Explanation:

The molartity is moles of compound (in this case KBr) in 1 liter of solution :

2 L3, 7 moles KBr

1 L..x= (1L x3, 7 moles KBr)/2L= 1,85 moles KBr--> 1,85M

 The molarity is 1.85M  solution.                  

Explanation:

Molarity:

Molarity is defined as the molar concentration of a solution measured in moles of solute per liter of solution.

Given:

moles = 3.7

solution = KBr  dissolved in 2L of water

To calculate: molarity  

The formula of molarity:

Molarity= moles of solute/liters of solution

Solution:

Molarity= 3.7/2      

molarity= 1.85M solution

Therefore molarity of 3.7 moles of KBr dissolved in 2 L of water is 1.85M solution.
