Question

As an empty 1,000-mililiter container has a mass of 250.0 grams. When flled with a liquid, the container and the liquid have a combined mass of 1,300. grams. What is the density of the liquid?

Answer 1

`"Density,"` `rho="Mass of liquid"/"Volume"=1.05*g*mL^-1`

Explanation:

And thus we work out the quotient with the given data; note that we have to subtract the tare weight, i.e. the mass of the container:

`"Mass"/"Volume"=(1300*g-250*g)/(1000*mL)=(1050*g)/(1000*mL)`

`=1.05*g*mL^-1...................`
