Is this correct? ***a chemical formula shows the elements and ratio of atoms in a compound***

1.12g

Explanation:

Step 1:

The balanced equation for the reaction is given below:

Ba(NO3)2 + Na2SO4 —> BaSO4 + 2NaNO3

Step 2:

Let us calculate the mass of barium nitrate, Ba(NO3)2, that reacted and the mass of barium sulfate, BaSO4, produced from the balanced equation. This is illustrated below:

Molar Mass of of barium nitrate, Ba(NO3)2 = 137 + 2[14 + (16x3)] = 137 + 2[14 +48] = 137 + 2[62] = 137 + 124 = 261g/mol

Molar Mass of barium sulfate, BaSO4 = 137 + 32 + (16x4) = 137 + 32 + 64 = 233g/mol

Step 3:

Determination of the theoretical yield of barium sulfate, BaSO4. The theoretical yield of barium sulfate, BaSO4 can be obtained as follow:

From the balanced equation above, 261g of Ba(NO3)2 produced 233g of BaSO4.

Therefore, 1.25g of Ba(NO3)2 will produce = (1.25 x 233)/261 = 1.12g of BaSO4.

Therefore, the theoretical yield of barium sulfate, BaSO4 is 1.12g
