<h2>Its <u>(C)</u> I guessed it and got it wrong just so I can give the answer away.</h2>
Answer: C
Explanation: This is because of a nice thing called guessing
For a molecule AB2, 3.5g of A represents one molar fraction, and 8.00g B represents 2 molar fractions (or 4.0+4.0). Therefore, a direct ratio can be given as 3.5:4.0, or 1:1.14. This means a molecule AnBm will give a mass ratio for A:B of n:1.14xm
For a molecule AB, for every 1g of A, you will have 1.14g of B.
For a molecule AB2, for every 1g of A, you will have 2.28g of B.
For a molecule A2B3, for every 1g of A, you will have (1.14x3/2) 1.71g of B.
