Please help me with these AP CHEM homework problems problems and show me the steps:
Mass per Volume Results for Titrations: Determine the mass per volume results requested in the following problems.
#23) A particular water supply is found to contain 0.000160 MAs, what is the concentration as milligrams As per liter of water?
#26) A sample if blood is analyzed for total calcium, the result (0.00236 Mcalcium) is very near the middle of the normal range for adults (8.5-10.5 mg/dL). Use unit conversions to determine the milligram per deciliter (mg/dL) concentration of calcium in the 0.00236Mcalcium blood sample?
1000 milligrams = 1grams
10 deciliter = 1 liter
