Initially a beaker contains 225.0 ml of a 0.350 m mgso4 solution. then 175.0 ml of water are added to the beaker. find the concentration of the final solution. what is the volume?

Answer : The concentration of final solution is, 0.197 M and the final volume of solution is, 400 ml

Solution :

First we have to calculate the final volume of solution.

Final volume of solution = Volume of + Volume of water added

Final volume of solution = 225.0 ml + 175.0 ml = 400 ml

Now we have to calculate the concentration of final solution.

Formula used :

where,

= concentration of solution = 0.350 M

= volume of solution = 225.0 ml

= concentration of final solution = ?

= volume of final solution = 400 ml

Now put all the given values in the above formula, we get the concentration of final solution.

Therefore, the concentration of final solution is, 0.197 M

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
