Compound 2 contains 2.0g of hydrogen and 32.0g oxygen. What is the percent compound of each element?

Sagot :

Note down the formula below

[tex]\boxed{\sf Mass\%\;of\; element=\dfrac{Mass\:of\:the\: element}{Mass\;of\:the\: compound}\times 100}[/tex]

Mass of the compound

[tex]\\ \sf\longmapsto 32+2=34g[/tex]

Mass % of Hydrogen:-

[tex]\\ \sf\longmapsto \dfrac{2}{34}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{1}{17}\times 100[/tex]

[tex]\\ \sf\longmapsto 5.8\%[/tex]

Mass % of Oxygen:-

[tex]\\ \sf\longmapsto \dfrac{32}{34}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{16}{17}\times 100[/tex]

[tex]\\ \sf\longmapsto 94.2\%[/tex]
