A scientist from chile has transported volcanic ash samples to be tested in his lab if the scientist has 3540 grams of volcanic ash and the ash has a density of 2.75 g/cm how many cubic centimeters of ash has he brought to the lab

3,540 grams of ash

If its density is 2.75 g/cc and

density = mass / volume then its volume is

volume = mass / density

volume = 3,540 g / 2.75 g / cc

volume = 1287.272727 cc

So, rounded it is 1,287.3 cubic centimeters but to keep the same number of significant figures, the volume is

volume = 1,287 cc
