Hello!

The answer is:

The density is equal to:


78.6(lb)/(ft^(3) )

Why?

This a unit conversion problem, so, converting the density of glycerin from
gram/cm^(3) to
(lb)/(ft^(3)) using the given conversion rates, we have:


1.26(gram)/(cm^(3))*(1lb)/(454gram)*(28317cm^(3) )/(1ft^(3) )=78.59(lb)/(ft^(3) )

Rounding to three significant figures, we have that the density is equal to:


78.6(lb)/(ft^(3) )

Have a nice day!
