Identify how many moles are in 3.01 x 10 exp 21 molecules

There are 0.005 mol in that amount of molecules.

Step-by-step explanation:

A mol has 6.02*10^(23) molecules, therefore in order to calculate the number of moles that are in 3.01*10^(21) molecules, we need to divide it by the number of one mol. This is done below:

number of moles = number of molecules / 6.02*10^(23)

number of moles = 3.01*10^(21)  / 6.02*10^(23)

number of moles = 0.5*10^(21 - 23)

number of moles = 0.5*10^(-2) = 0.005 mol

There are 0.005 mol in that amount of molecules.

i belive those are the ones that are under 90 degreese.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
