The concentration of dye in solution a is 20.422 m. a serial dilution is performed to make solutions b and c. in the first dilution, 2 ml of solution a is diluted with 12 ml water to make solution b. then, 2 ml of solution b is then diluted with 1 ml of water to make solution c. what is the concentration of dye in solution c? provide your response to three significant figures in units of molarity.

1.95 M

Explanation:

Considering

Moles of A = Moles of B

Or,

Given  that:

So,  

Molarity of solution B = 2.92 M

Again Considering,

Moles of B = Moles of C

Or,

Given  that:

So,  

Molarity of solution C = 1.95 M

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
