Question

25ml of 3 moles HNO3 is mixed with 75ml of 4moles HNO3 if thier volumes are adittive than what would be the molarity?

Answer 1

PLEASE GIVE ME A BRANLIAST ANSWER

Answer:- Molarity of the mixture solution is 3.75M.

3.0(25) + 4.0(75) = M(25+75)

75 + 300 = M(100)

375 = M(100)

M=\frac{375}{100}

M = 3.75

The final mixture will be =3.75

OR

Solution:- Volume is an additive property so the volume of the mixture would be the sum of the volumes of two solutions of the acid being added together.

We could easily solve this problem using dilution equation:

Where, M and V are the molarity and volume of the mixture.

Let's plug in the values in the equation:

3.0(25) + 4.0(75) = M(25+75)

75 + 300 = M(100)

375 = M(100)

M = 3.75

So, the molarity of the mixture solution is 3.75M.
