What do a 12.01 g sample of carbon and 24.3 g sample of magnesium have in common?

A. They have the Same density
B. Each contains 0.5 moles of particles
C. Each contains 6.02 x 10^23 atoms
D. They have the same number of valence electrons

Option C. Each contains 6.02 x 10^23 atoms

Explanation:

From Avogadro's hypothesis, 1mole of an element contained 6.02x10^23 atoms.

If this is so, all elements therefore have the same number of atoms present in them.

1 mole of carbon = 12. 01g/mol = 6.02x10^23 atoms.

1 mol of magnesium = 24.3g/mol = 6.02x10^23 atoms.

From the above we can see that 12.01g of carbon and 24.3g magnesium both have 6.02x10^23 atoms.

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
