Compound 2 contains 2.0g of hydrogen and 32.0g oxygen. What is the percent compound of each element?
Dmitriy789 [7]

Note down the formula below

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

Mass of the compound

\\ \sf\longmapsto 32+2=34g

Mass % of Hydrogen:-

\\ \sf\longmapsto \dfrac{2}{34}\times 100

\\ \sf\longmapsto \dfrac{1}{17}\times 100

\\ \sf\longmapsto 5.8\%

Mass % of Oxygen:-

\\ \sf\longmapsto \dfrac{32}{34}\times 100

\\ \sf\longmapsto \dfrac{16}{17}\times 100

\\ \sf\longmapsto 94.2\%
