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

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
