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?

Sagot :

Find the molar mass of CaCO3 then subtract the molar mass what it originally weighed and the loss of mass. Hopefully this works!
