What size volumetric flask would you use to create a 0.50 M
solution using 10.00 g of CaBr2

Explanation:

First convert the grams of Calcium Bromide to moles by using the atomic weight. Then use the formula for molarity, which is moles per liter.

CaBr2 = 199.9 g/mol

10/199.9 = 0.05 moles of CaBr2

x = 0.1L or 100mL

the answer is 0.8m.
