Question

Доля кислорода в польметиленовой кислоте

Answer 1

Пальмитиновая кислота CH3(CH2)14COOH
M(CH3(CH2)14COOH) = 15+14x14+12+16x2+1 = 256 г/моль
W(O2) = 2A(O)/M(CH3(CH2)14COOH) = 2x16/256 = 0,125 или 12,5 %

Answer 2

Polymethylene Glycolic Acid Oxygen Content

The oxygen content in polymethylene glycolic acid is approximately 0.65% to 0.35%. This can be expressed as 0.0065 to 0.0035 in decimal form.

The molecular formula for oxygen is O, and its molar mass is approximately 15.9994 g/mol
