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:-

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

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

$\\ \sf\longmapsto 94.2\%$
