Mgcl2 has a formula weight of 95g. mol-1. how would you make 10 ml of a 0.1 m solution of mgcl2.

moles = conc x vol  

moles = 0.1 x 0.010 = 0.001 moles  

mass = moles x molar mass  

mass = 0.001 moles x 95 = 0.095 g

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
