Question

find the number of moles of the substance NAOHwhich has 3.011×10^21molecules
​

Answer 1

Answer:

0.005 moles

Explanation:

each mole of any substance has

6.022×10^23 atoms or molecules

(depending on if it is element,compound respectively)

so 1mole NaOH=6.022×10^23 molecules

3.011×10^21 molecules

=(3.011×10^21)/(6.022×10^23) moles

=1/200 moles

=0.005 moles
