Calculate the molarity of a MgSO4 solution prepared by adding 0.27 moles of MgSO4 to
enough water to make 7 L of solution.
Answer in units of M.

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
