Add 3685 g and 66.8 kg and express your answer in milligrams (mg).
Select one:
a. 7.05
3685 g and 66.8 kg
3685 g = 3.685 kg
3.685 kg +66.8 kg = 70.5kg
70.5 kg = 7.05 *10^7 mg
(1mg = 10^6 kg)
Add 3685 g and 66.8 kg and express your answer in milligrams (mg). Select one: a....
Calculate the concentration of Br (MW = 79.904 g/mol), in milligrams per milliliter (mg/mL), in an aqueous solution that is 1.17 wt% MgBr, (MW = 184.113 g/mol). The density of this solution is 1.10 g/mL. Note that significant figures are graded for this problem. Be sure you do not round your answers until the very end of your calculations. concentration: mg/mL TOOLS x10'
