I have a family. I love all my family, mother, father and sister. Family for me - it`s a very important thing. And all family members getting an influence on me.
I like to do many interesting things with my family. We have different hobbies, but do many activities together. We playing computer games, watching TV, listening to music.
If you want to have such a happy family, as me, you should love all your relatives. Don`t swear with them, and follow their interests.
I want to ask British people, how do they keep their families always happy and what should I do in order not to upset my family?
Рассчитаем молярную массу вещества 1,59Х29=46г/моль
Найдём массу углерода ( 4,4х12)/44=1.2
Найдём массу водорода(2,7х2)/18=0,3
В состав искомой формулы входит кислород 2.3-(1,2+0,3)=0,8
Представим искомую формулу в виде СхHyOz
Найдём число атомов x,y,z
x:y:z=1,2/12:0,3:0,8/16=0,1:0,3:0,05=2:6:1
Подставляем найденные значения в формулу-получаем С2Н6О-простейшая формула
Найдём молярную массу данного вещества
М( С2Н6О)=46г/моль
Следовательная данная простейшая формула является истиной
ответ: С2Н6О
