Acompound's percent composition is 75% c and 25% h. what is the empirical formula of the compound?

CH4

If the compound has 25% hydrogen and 75% carbon, assume there is a 100 g sample composed of 25 g of hydrogen and 75 g of carbon. Use the molar mass of each element to convert the gram amounts to moles and you have 25 moles of hydrogen and 6.25 moles of carbon. Divide each by 6.25 and you have 4 moles of hydrogen for 1 mole of carbon and an empirical formula of CH4

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
