Some fertilizer blends contain magnesium nitrate (mgno3). suppose that a chemist has 1.24 liters of a 2.13 m solution of magnesium nitrate. if the chemist dilutes the solution to 1.60 m, what is the volume of the new solution? express your answer to three significant figures. the volume of the new solution is liters.

1.65 litres is your answer

Answer : The volume of new solution is, 1.65 liter

Solution :

According to the dilution,

where,

= molarity of magnesium nitrate solution = 2.13 M

= volume of magnesium nitrate solution = 1.24 L

= molarity of new solution = 1.60 M

= volume of new solution = ?

Now put all the given values in the above law, we get the volume of new solution.

Therefore, the volume of new solution is, 1.65 liter

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
