$rho_"density"$ is given by the quotient.... $rho="mass"/"volume"$...and clearly has associated units of $g*mL^-1$. Here we take the quotient $rho=(43*g)/(50*mL)-=??*g*mL^-1$.. And so would the oil float on water? Why or why...

1 Answers 1 viewsAnd should I multiply $"mass"/cancel"charge"xxcancel"charge"$, I should get an answer of $"mass"$. Let's see: $5.64xx10^-12*kg*cancel(C^-1)xx1.605xx10^-19*cancelC$ $~=1xx10^30*kg$ for a single electron. Well, I got the units of mass, which...
