Use Avogadro's number which is numerically equal to ...
( 6.02 multiply by 10 to the power of negative 23)
Avocado's number is the number of particle(molecules, ions, atoms) present in one mole of substance.
number of molecule in 0.809 mole of h20 = ....
one mole of h20 contains (6.02* 10^-23)
0.809 mole contains....(6.02* 10^-23) (0.809)
which is equal to [4.951* 10 ^-23]
if I made no mistake in calculation...it must be correct
Their path fluctuates to the north or south depending on the location of hot and cold air masses
Answer : The chain of many building blocks can be called as polymers in general.
Explanation : Polymers are large units of molecules in structure which are combined by the smaller repeating units called as monomers. Every macromolecule can be defined differently, like proteins are polymers made up of amino acids. Cellulose is a polymer made up of glucose monomers. The building blocks of nucleic acids are called as nucleotides.
If you go by the decimal there should be 5 significant digits because 0 is a trailing zero and matters since it comes after a decimal. however if you do
6.3590 x 10 ^7 = 63590000 then you would only have 4 significant digits because there is no longer a decimal to make the zero after the 9, significant.
Hope this helps!
