Before the lab students needed to make the necessary chemical reagent solutions, the teacher asked them to make 50.0 mL of 1.0 M H2SO2 from a 6.0 M sock solution M1 =
V1 =
M2 =
V2 =

(Please help I had surgery so I didn’t even learn this lesson and literally none of my friends know either)

All of the following are part of the biosphere except

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.

The molecular weight of carbon dioxide, co2, is 44.00 amu, and the molecular weight of nitrous dioxide, no2, is 46.01 amu, so no2 diffuses co2
