A test tube containing CaCO₃ is heated until the entire compound decomposes. If the test tube plus calcium carbonate originally
weighed 30.08 grams and the loss of mass during the experiment was 4.40 grams, what was the approximate mass of the empty test tube? A. 20.08 g
B. 21.00 g
C. 24.50 g
D. 25.08 g
E. 25.68 g
Can anyone explain this one for me?
C is the correct answer because density is mass per unit volume and when you divide it we that volume is greater than mass so density is less density density is directly proportional to Mass Density is inversely proportional to volume
