Vasiliev Chapter 6 Problem 81

6.81. A sample of an organic compound consisting of C, H, O weighing m1 (g) was burned to CO2 and H2O. The increase in the mass of the tube with alkali due to the absorption of CO2 was m2 (g). The increase in the mass of the tube filled with CaCl2 due to the absorption of H2O was m3 (g). Calculate the mass fractions (%) of C, H and O in the analyzed compounds and give their empirical formulas:

Option m1, g m2, g m3, g
1 0.0382 0.0729 0.0448
2 0.0432 0.0949 0.0519
3 0.0311 0.0621 0.0254
