Given the data you collected for the volume of water displaced by 25.000 g of aluminum, what is the density of aluminum? A. 3.38 g/cm
B. 13.5 g/mL
C. 2.70 g/cm
D. 0.637 g/mL

C. 2.70 g/mL

Explanation:

Density is the ratio between the mass of a substance and the volume it occupies. Based on Archimedes' volume, the displaced volume of the aluminium is the volume it occupies. To solve this question we must find the difference in volume between initial volume of water = 30mL and final volume of water + aluminium = 39.26mL. This difference is the volume of the aluminium. With its mass we can find density:

39.26mL - 30mL = 9.26mL

Density = 25.00g / 9.26mL =

2.70g/mL

Right answer is:

i just learnt this recently but i need to look through my notes again
