Calculate the mass of oxygen in 350 g of al(c2h3o2)3 a 57 grams b 164.5 grams c 39.17 grams d 19.58 grams

-

164.5 grams of oxygen is present in 350 g of Al(C₂H₃O₂)₃

Explanation: -

Molar mass of Al(C₂H₃O₂)₃ = 27 x 1 + 12 x 6 + 1 x 9 + 16 x 6

= 204 g

Mass of oxygen present in 204 g of Al(C₂H₃O₂)₃ = 16 x 6 = 96 g

204 g of Al(C₂H₃O₂)₃ contains 96 g of oxygen.

350 g of Al(C₂H₃O₂)₃ contains of oxygen

= 164.5 grams

Thus 164.5 grams of oxygen is present in 350 g of Al(C₂H₃O₂)₃
