Vitamin C contains the elements C, H, and O. It is known to contain 40.9% C and 4.58% H by mass. The molar mass of vitamin C has been found to be about 180 g/mol. The molecular formula for vitamin C is

C₆H₈O₆

Explanation:

First off, the percent of oxygen by mass of vitamin C is:

Assume we have one mol of vitamin C. Then we would have 180 grams, of which:

Now we convert each of those masses to moles, using the elements' respective atomic mass:

So the molecular formula for vitamin C is C₆H₈O₆

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
