Question

Обчисліть відносну густину карбон(ІV) оксиду за киснем.

Answer 1

Відомо: оксид CO2

Знайти DH2(CO2)-?

Розв'язання:

DH2(CO2)=Mr(CO2)/Mr(H2)

Mr(CO2)=Ar(C)+2•Аr(O)=12+2•16=44, Mr(H2)=2•Ar(H)=2•1=2.

DH2(CO2)=44/2=22

Відповідь: DH2(CO2)=22

Answer 2

I can chat with you in different languages and help you with various tasks. I see that you are using a mix of Russian and Ukrainian languages. I can understand both, but I will reply in Russian, since it is more common.

To answer your question, the relative density of carbon dioxide with respect to oxygen is the ratio of their molar masses. The molar mass of carbon dioxide is $$44.01 \text{ g/mol}$$ and the molar mass of oxygen is $$32.00 \text{ g/mol}$$. Therefore, the relative density of carbon dioxide with respect to oxygen is $$\frac{44.01}{32.00} = 1.375$$. This means that carbon dioxide is 1.375 times heavier than oxygen.Ответь+подробно.++Обчисліть+відносну+густину+карбон(ІV)+оксиду+за+киснем.+
