A chemist must prepare 700.mL of 1.00M aqueous calcium bromide CaBr2 working solution. He'll do this by pouring out some 1.95M aqueous calcium bromide stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the calcium bromide stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.

359. mL is the volume of the calcium bromide stock solution that the chemist should pour out.

Explanation:

Molarity of the calcium bromide solution=

Volume of calcium bromide solution to be diluted =

Molarity of the calcium bromide solution after dilution =

Volume of calcium bromide solution after dilution =

Dilution eqaution is given as:

359. mL is the volume of the calcium bromide stock solution that the chemist should pour out.

the ratio of the conjugate base to the acid required to attain the desired ph.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
