Ethane and acetylene are two gaseous hydrocarbons. Chemical analyses show that in one sample of ethane, $2.65 \mathrm{g}$ of carbon are combined with $0.665 \mathrm{g}$ of hydrogen, and in one sample of acetylene, $4.56 \mathrm{g}$ of carbon are combined with $0.383 \mathrm{g}$ of hydrogen.(a) Are these results consistent with the law of multiple proportions? (b) Write reasonable molecular formulas for these compounds.

Reasonable molecular formulae Ethane: $C_{2} H_{6}$ Acetylene: $\mathrm{C}_{2} \mathrm{H}_{2}$

to solve this problem. First, we need to review the concept of the law of manageable proportions. So this last days that when two elements combined to form more than one compounds, um, us off one element which combats with a fixed mass off the azar, adamant will always be ratios of whole numbers. Okay, so let's take a look at this question. We have a thumb and a Sageman. So in a sense, we have 2.65 grams off Carmen and points 665 rooms off fashion if we want to fix one elements. So let's fix the carbon. Okay. Uh, we give added to the cup by 2.65 forms divided both sides now is a carbon. It's one gram and the Hashan is point. It's 0.25 grams. So in one run off carbon there 0.25 grams of passion. Ethan, no way would do the same for ssh in if we fix the carbon. So being a divide both sides by 41 56 worms than the mass for common is wing room and the passion ISS points. There are 84 grands. So the last states that's the ratio off the masses off. The second elements can always be reduced to small whole numbers. Now let's look at the ratio. OK, so points to a flat. Graham Stephen did abide. They will 0.84 grams. The ratio is roughly three to one. So this is a whole number. That means these results are consistent with law off multiple proposes. So we're writing the phone allows for even and a statement because ratio we calculated is free to one. So, um reasonable. More across B C two h six for season and C two h two for a sage notes that the subscript of Hashim the ratio off these two passion adamant 6/2, which is 3/1, so that's originally got before.
