When barium (ba) reacts with sulfur (s) to form barium sulfide (bas), each ba atom reacts with an 5 atom. if 250 cm3 of ba reacts with l75 cm3 of s. are there enough ba atoms to react with the s atoms (d of ba = 3.51 g/cm3; dof s = 207 g/cm3)?

No, there are not enough Ba atoms

Explanation:

Mass of of Ba =

Mass of of S =

Molar mass of Ba = 137.33 g

Molar mass of S = 32.06 g

1 mol of an element contains number of atoms.

So 8.775 g of Ba =

So 3.6225 g of S =

As 1 atom of Ba reacts with 1 atom of S therefore enough Ba atoms are not present for reaction.
