$sf((a))$

$sf(463color(white)(x)g)$

$sf((b))$

$sf(3.7color(white)(x)L)$

(a)

Use the idea that:

Density = mass / volume.

In symbols:

$sf(d=m/v)$

The question is using both $sf(cm^3)$ and $sf(ml)$ which are the same.

So:

$sf(m=d.v=1.11xx417=462.87color(white)(x)g)$

$sf(m=463color(white)(x)g)$ to 3sf.

(b)

Rearranging we get:

$sf(v=m/d)$

We now need to convert $sf(kg)$ into $sf(g)$ which we do by multiplying the mass by 1000 $sf(rArr)$

$sf(v=(4.1xx10^3)/(1.11)=3693.7color(white)(x)ml)$

$sf(v=3.7color(white)(x)L)$
