Given #rho_"substance"=2.78*g*mL^-1#, what volume is associated with a #32.0*g# mass?
I write the defining quotient because given two of the three properties, we can access the third by division or multiplication.....
Here we gots
And so, clearly, we can calculate
Such an operation is also consistent dimensionally, which is why I include the units of each property. We want an answer with units of density,
