Chemistry ! : neon has an average atomic mass of 20.2 g/mol, whereas argon has an average atomic mass of 40.0 g/mol. how would the number of atoms in a 1.0 mol sample of neon compare to the number of atoms in a 4.0 mol sample of argon? (2 points) a. the argon sample would have the same number of atoms as the neon sample. b. the argon sample would have twice as many atoms as the neon sample. c. the argon sample would have four times as many atoms as the neon sample. d. the argon sample would have eight times as many atoms as the neon sample.

C. The argon sample would have four times as many atoms as the neon sample.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

1 mole of neon contains= atoms

1 mole of argon contains=  atoms

Thus 4 moles of argon contains=  atoms

Thus the argon sample would have four times as many atoms as the neon sample.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
