How many atoms are there in 0.57 mol of Zn

3.43 * 10^23 atoms of zinc

Explanation:

According to Avogadro's law, one mole of a substance contains a certain number of atoms of the substance commonly referred to as the Avogadro's number.

We already know from Avogadro's law that;

1 mole of zinc contains 6.02 * 10^23 atoms of zinc

Therefore;

0.57 mole of zinc will contain 0.57 * 6.02 * 10^23/1

which gives us 3.43 * 10^23 atoms of zinc

put the answers   and i could answer.

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.
