What is the molarity of a solution that contains 0.30 moles of KBr in 400 mL of solution. Please show all work
Molarity= moles solute/volumeinliters
= .3/.4
Why do you shout your name? (MEGAN!!!!). I hope your mom doesn't do that.
haha thanks bob :) lol i do it so my name is more noticeable!
To calculate the molarity of a solution, you need to use the formula:
Molarity (M) = moles of solute / volume of solution in liters
First, convert the volume of the solution from milliliters to liters:
400 mL ÷ 1000 mL/L = 0.4 L
Now, substitute the given values into the formula:
Molarity (M) = 0.30 moles / 0.4 L
Finally, divide the moles of solute by the volume of solution:
Molarity (M) = 0.30 moles / 0.4 L = 0.75 M
Therefore, the molarity of the solution containing 0.30 moles of KBr in 400 mL of solution is 0.75 M.
