Answer:
The molarity is : 1, 85M
Explanation:
The molartity is moles of compound (in this case KBr) in 1 liter of solution :
2 L----------3, 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.
