Answer:

Using conversion factors, we get #23mL#.

Explanation:

We can answer this question using conversion factors.

In short, since we know that #1.48# grams of the substance is equal to #1cm^3# of the substance, we know that #(1cm^3)/(1.48g)=1#

Also, since #1mL# is equal to #1cm^3#, we can say that #(1mL)/(1cm^3)=1#

Then, all we need to do is multiply our value (#34g#) by the conversion factors.

#34color(green)g*color(red)(1cm^3)/(1.48color(green)g)*(1mL)/color(red)(1cm^3)#

The same-colored units cancel out, and we're left with:

#(34mL)/1.48#

#34mL# has two significant figures, so we give our answer to two significant figures:

#23mL#
