How many molecules are there in 65 g of silver nitrate (agno3)?

Answer : The number of molecules present in 65 g of silver nitrate are,

Solution : Given,

Mass of silver nitrate = 65 g

Molar mass of silver nitrate = 169.87 g/mole

First we have to calculate the moles of silver nitrate.

Now we have to calculate the number of molecules present in silver nitrate.

As, 1 mole of silver nitrate contains number of molecules

So, 0.382 mole of silver nitrate contains number of molecules

Therefore, the number of molecules present in 65 g of silver nitrate are,

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

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.
