if you have 2 solutions for example
50ml of 0.5M of a solution (A)
and 0.25M of 100ml of a solution (B)
Would the new volume be 150ml or 0.150L
And would I have to change the molarity of solutions A and B

Those are the same value.
> And would I have to change the molarity of solutions A and B
The molarity of the mixed solution is different from the molarity of solutions A and B, if that’s what you’re asking.
Remember what molarity means: it means the number of moles of whatever the dissolved substance is, divided by the number of liters it’s dissolved in. To find the molarity of the mixed solution, figure out how many moles of the substance are in the mixture (hint: it’s the number of moles of the substance that were in mixtures A and B, added together – the *molarities* don’t add, but the *number of moles* does).
