We’re being asked to identify plausible sets of formulas for two compounds.
We’re given a 1.00-g sample of each compound. One sample contains 0.25 g of X and the other contains 0.33 g of X.
mass X = 0.25 g
mass Y = 1.00 g – 0.25 g = 0.75 g
mass X = 0.33 g
mass Y = 1.00 g – 0.33 g = 0.66 g
Let's take look at each option given:
XY3 and XY4
Let's use a hypothetical molar mass for X and Y to get XY3.
Suppose there are two known compounds containing the generic elements X and Y. You have a 1.00-g sample of each compound. One sample contains 0.25 g of X and the other contains 0.33 g of X.
Identify plausible sets of formulas for these two compounds. Check all that apply.
