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 MgSO_4 + 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 :

C_1V_1=C_2V_2

where,

M_1 = concentration of MgSO_4 solution = 0.350 M

V_1 = volume of MgSO_4 solution = 225.0 ml

M_2 = concentration of final solution = ?

V_2 = volume of final solution = 400 ml

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

(0.350M)\times (225.0ml)=C_2\times (400ml)

C_2=0.197M

Therefore, the concentration of final solution is, 0.197 M

Suppose you determined the density of a cube to be 1.40 g/cm3. would the density of the cube be different if you had a cube made
ki77a [65]
Density is mass/volume so if you double the mass you would also double the volume which means density would stay the same. Density is the amount of of matter in a given area and it is constant for the substance regardless of differences in mass or volume.

HELP! <br><br>How many moles of a solute would 3 liters of a 2-molar solution contain? ​
katrin [286]

Answer: If it was 3 mol of solute in 2 L of solution it would be 1.5 mol/L.

However when the solute dissolves in the water creating the solution, the volume increases. So 3 mol of solute in 2 L of water creates more than 2 L of solution.

The correct method for making a 3 mol/L solution would be to place some water into a two liter volume container. Dissolve all 3 mol of the solute into the water. Then add water to the 2 L mark. Now there is 3 mol of solute and 2 L of solution.
