Calculate the concentration of a solution made by diluting 86.0 mL of 4.4 M HBr to a final volume of 575.0 mL. Significant figures are graded for this problem. Be sure you do not round your answers until the very end of your calculations.

0.658M

Explanation:

The following were obtained from the question given:

C1 = 4.4 M

V1 = 86mL

C2 =?

V2 = 575.0 mL

Applying the dilution formula:

C1V1 = C2V2

4.4 x 86 = C2 x 575

Divide both side by 575

C2 = (4.4 x 86) /575

C2 = 0.658M

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

the answer is na (sodium)
