Question #cddba

Answer 1

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`
