Question

Сколько граммов воды и сколько миллилитров воды надо добавить в 200г. 96%раствора кислоты , чтобы получить 49%

Answer 1

M(кислоты)=w*m(раствора)0,96*200=192г
192=0,49*(200+х)
94=0,49х
х=192г нужно добавить

Answer 2

Calculation of Water and Acid Solution

To determine the amount of water and acid solution needed to obtain a 49% solution from a 200g 96% acid solution, we can use the concept of dilution.

The formula for dilution is:

C1V1 = C2V2

Where: - C1 is the initial concentration of the acid solution (96%) - V1 is the initial volume of the acid solution (200g) - C2 is the final concentration of the desired solution (49%) - V2 is the final volume of the desired solution (which we need to find)

We can rearrange the formula to solve for V2:

V2 = (C1V1) / C2

Let's substitute the given values into the formula:

V2 = (96% * 200g) / 49%

Now, let's calculate the value of V2:

**V2 = (0.96 * 200g
