What volume (ml) of a concentrated solution of magnesium chloride (9.00 m) must be diluted to 350.0 ml to make a 2.75 m solution of magnesium chloride?

The 106.94 ml of 9.0 M concentration magnesium chloride is diluted to 350 ml to make the solution of 2.75 M .

For diluting the solution to a specific concentration, following formula is used:

C1 and V1 are the concentration and volume of known solution.

C2 and V2 are the concentration and volume of the unknown solution.

From the question,

9 M V1 = 2.75 M 350 ml

Volume of 9.0 M solution required = 2.75 M 350 ml / 9

Volume of 9.0 M solution required = 106.94 ml.

The 106.94 ml of 9.0 M concentration magnesium chloride is diluted to 350 ml to make the solution of 2.75 M .

i just learnt this recently but i need to look through my notes again

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.
