C(x)H(y) + O(2)= x CO(2)+ y/2 H(2)0 

 

x=13.2/44=0.3

y/2=2.7/18=0.15

 

 M=3.482*22.4 =77.9968 - молярная масса

Исходное вещество С6H6

На доске подряд выписаны натуральные числа от 1 до 30. Сначала с доски стерли все нечетные числа. Из оставшихся чисел стирают все числа, оказавшиеся на четных местах. Затем снова стирают все числа, оказавшиеся на нечетных местах, и так далее, пока не останется одно число. Какое?
