A solution is prepared by dissolving 0.400 g of solute in 1000.g of water.How many parts per million of solute are in this solution?
A)0.400 ppm
B)4.00 ppm
C)400.ppm
D)4000 ppm

Parts per million (ppm) is a unit of concentration, which can be calculated as:
(ppm) = (mass of solute / mass of solution) * 10^6
In this case, the mass of solute is 0.400 g, and the mass of solution is 1000. g. Substituting these values into the formula, we get:
(ppm) = (0.400 / 1000) * 10^6
(ppm) = 400
Therefore, the answer is C, 400 ppm.
