Given data:

Number of moles = ?

Mass = 148.6 g

Solution:

Number of moles = mass/ molar mass

Molar mass of CH₄ = 16 g/mol

Now we will put the values in formula.

Number of moles = 148.6 g/ 16 g/mol

Number of moles = 9.29 mol

Thus 148.6 g have 9.29 moles.

Answer: The gas generated by two antacid tablets has a smaller volume.

Explanation:

(800•500) = (200•V2)
and then we get that
V2= 2000 ml
