What will be the volume of a gas satriple at 309 K if its volume at -58 C is 3.42 L? Assume that pressure is constant.

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. one of these isomers has a heat of hydrogenation of 101 kj/mol (24.1 kcal/mol), and the heat of hydrogenation of the other is 113 kj/mol (27.1 kcal/mol). match the heat of hydrogenation with the appropriate dihydronaphthalene.

Calculate the number of moles of ethane in 100 grams

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
