Given that Avogadros's number is 6.02x10^23. Calculate the numbe of molecules present in 5.0moles of nitrogen gas -N2(g)
1 mol contains 6.2E23 so 2 mols contain ....., 3 mols contain ......, 4 mols contain ..... and 5 mols contain .....?
To calculate the number of molecules present in 5.0 moles of nitrogen gas (N2), we can use Avogadro's number.
Avogadro's number tells us the number of molecules in one mole of any substance. It is approximately 6.02x10^23 molecules/mol. Therefore, 1 mole of any substance will contain 6.02x10^23 molecules.
To find the number of molecules in 5.0 moles of nitrogen gas (N2), we need to multiply Avogadro's number by the number of moles:
Number of molecules = Avogadro's number x Number of moles
Number of molecules = (6.02x10^23 molecules/mol) x (5.0 moles)
Now, let's substitute the values into the equation and calculate:
Number of molecules = (6.02x10^23) x (5.0)
Number of molecules = 3.01x10^24 molecules
Therefore, there are approximately 3.01x10^24 molecules in 5.0 moles of nitrogen gas (N2).
