The amounts of two elements X and Y in three samples of an unknown substance are as follows: 10.0 g X and 10.0 g Y in Sample 1 18.0 g X and 12.0 g Y in Sample 2 6.0 g X and 2.0 g Y in Sample 3 What is this substance? Hint: Compare the percentages of Y (or X) in each sample. Are these percentages of Y the same or different? I will say that in sample 1 the percentage of Y is 50 %. likely a mixture likely a compound likely an element either a compound or an element, but cannot be a mixture
