WebExample 2: Show that 1 mole of 12C is 12g. Recall that, 1 amu = 1.6605 x 10^ (-27) kg and 1 mole = 6.02 x 10^23. 12C = 12 amu Therefore, 1 mole of 12C = 1 mole of 12 amu = 1 mole of 12 x 1.6605 x 10^ (-27) kg = 6.02x10^23 of 12 x 1.6605 x 10^ (-27) kg = 6.02x10^23 x 12 x 1.6605 x 10^ (-27) kg = 0.012 kg = 12g WebSep 3, 2024 · These coefficients also have the ratio 2:1:2 (check it and see), so this equation is balanced. But 6.022 × 10 23 is 1 mol, while 12.044 × 10 23 is 2 mol (and the number is written that way to make this more obvious), so we can simplify this version of the equation by writing it as s1 eighth\u0027s
