How much dry substance is there if we have 150g of 8% of a solution of this substance.

if it's 8% by weight, then

.08 * 150

And the wording should be

150g of an 8% solution

43

To determine the amount of dry substance in a solution, you need to multiply the volume of the solution by the percentage of the dry substance.

Step 1: Convert the percentage to decimal form.
8% = 8/100 = 0.08

Step 2: Multiply the percentage by the weight of the solution.
0.08 * 150g = 12g

Therefore, there is 12g of dry substance in a 150g solution with 8% concentration.

To calculate the amount of dry substance in a solution, you need to know the concentration of the solution and the total mass of the solution. In this case, the concentration of the solution is 8% and the total mass of the solution is 150g.

Step 1: Convert the concentration from a percentage to a decimal.
The concentration of 8% can be written as 0.08.

Step 2: Calculate the mass of the dry substance using the formula:
Mass of dry substance = (Concentration x Total mass of the solution)

Mass of dry substance = (0.08 x 150g)
Mass of dry substance = 12g

Therefore, there is 12g of dry substance in the 150g solution.
