If you have a 1234 gram sample of C4H7NO4, how many gams of Carbon would

be present?

445.4 grams of carbon would be present.

Explanation:

According to avogadro's law, 1 mole of every substance contains avogadro's number of particles and weighs equal to its molecular mass.

To calculate the moles, we use the equation:

As 1 mole of gives = 4 moles of carbon

Thus 9.28 moles of gives = moles of carbon

Mass of carbon =

Thus there are 445.4 grams of carbon would be present.

oh it is true if thats what you are asking

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
