A 2.75 kg sample of a substance occupies a volume of 250.0 cm3. Find its density in g/cm3.



Under certain conditions, oxygen gas (O2) has a density of 0.00134 g/mL. Find the volume occupied by 250.0 g of O2 under the same conditions.

Answer: 1) 11g/cm3

Explanation: Start by finding how many grams 2.75 kg equals (2750). Then calculate density by dividing mass by volume (2750/250).

I hope this helps!
