This site reports that rho_"Al"=2.7*g*cm^-3

Explanation:

We know that rho, "density"="unit mass"/"unit volume"

And thus "mass"="density"xx"volume"

And thus, since 1*mL-=1*cm^3, we take the product........

"volume"xx"density"="mass"

So "mass"=rhoxx"volume"

=2.7*g*cancel(mL^-1)xx17.8*cancel(mL)=48*g

The given product is dimensionally consistent. We want an answer in grams, and the product gives us an answer in grams.
