1.you wish to make a 0.325 m hydrochloric acid solution from a stock solution of 3.00 m hydrochloric acid. how much concentrated acid must you add to obtain a total volume of 50.0 ml of the dilute solution? in ml

2.in the laboratory you dilute 4.35 ml of a concentrated 12.0 m perchloric acid solution to a total volume of 50.0 ml. what is the concentration of the dilute solution? m

5.42 mL needed to be added and 1.04 M of dilute solution

Explanation:

For both cases, you need to use the expression:

M1*V1 = M2*V2

where M and V are concentration and volume.

For the 1st question, we have both concentrations, but we do not have both volume so:

3 * V1 = 0.325 * 50

V1 = 0.325 * 50 / 3

V1 = 5.42 mL need to be added.

For question 2:

Same as above, with the difference that we need to calculate concentration so:

12 * 4.35 = M2 * 50

M2 = 12 * 4.35 / 50

M2 = 1.04 M is the concentration of the diluted solution

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

it's all four options.
