a 48 because it is a multiple of 12
Step-by-step explanation:
1 mole of any substance is approximately 6.022*10^23 atoms (Avogadro's number)
So
(4.90*10^31 atoms) * (1 mole / 6.022*10^23 atoms) = 8.14*10^7 moles
Answer:
you should go on cymath it helps alot
Step-by-step explanation:
I promise you it really helps it gives you the answers step by step.
(9)(27)+(2)(31)−28=n
Simplify:
(9)(27)+(2)(31)−28=n
243+62+−28=n
(243+62+−28)=n(Combine Like Terms)
277=n
Flip the equation.
n=277
Answer:
