May 15, 2017 · 36 neutrons. One way we have of differentiating between various nuclides of the same element is by writing the name of the element followed by a hyphen and the mass number of the …

Apr 2, 2017 · 28.3 ml M/V = D Mass divide by Volume = Density Mass = 540 grams Volume = unknown ml put in V Density = 19.5 g/ ml ( 540 g)/ V = (19.5 g)/ (ml) divide both sides by 19.5 grams 540 g/ …

Well, we need to make some assumptions...this is not a straightforward problem. For one, we ASSUME that a 15*g mass of salt is dissolved in an 85*g mass of water...and thus CLEARLY, we gots 15% …

"Volume" ~= 175*mL "Density", rho = "Mass"/"Volume" And thus, "Volume" = "Mass"/rho And now we put in some noombers: "volume"_"Hg" = (2.4*cancel (kg)xx10^3*cancelg ...
