Magnesium is lighter than other structural metals, so it is increasingly important in the design of more efficient vehicles. mg2+ ions are present in seawater, and the metal is often prepared by "harvesting" these ions and converting them to mg metal. the average magnesium content of the oceans is about 1270 g mg2+ per ton of seawater, and the density of seawater is about 1.03 g/ml. what is the molarity of mg2+ ions in seawater? the design for a concept car calls for 125 kilograms of magnesium per vehicle. how many gallons of seawater would be required to supply enough magnesium to build one of these cars?

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
