trying to find the percent yield for 4-methylcyclohexene used 3.7826g (approx 4mL) of 4-methylcyclohexanol 1.0mL 85% phosphoric acid 16 drops concentrated sulfuric acid obtained 2.1619g of product (4-methylcyclohexene) my calculations to this point. phosphoric acid: 1.0mL (1.885g/mL) = 1.885g *(0.85) = 1.553g*(1mol/97.995g) = 0.016mol*(96.17g/mol) = 1.539g 4-methylcyclohexene 4-methylcyclohexanol: 3.7826g(1mol/114.2g) = 0.0334mol *(96.17g/mol) = 3.173g 4-methylcyclohexene which of these would I use for the theoretical yield? phosphoric acid or 4-methylcyclohexanol

Phosphoric acid, H3PO4,H3PO4, has some important applications. It can be used to produce fertilizers and it is present in soft drinks. Phosphoric acid can be made from phosphorus in a two step process: Reaction 1: P4+5O2→P4O10P4+5O2→P4O10 Reaction 2: P4O10+6H2O→4H3PO4P4O10+6H2O→4H3PO4 What is the molar mass of phosphoric acid, H3PO4?H3PO4? Report your answer to 3 significant figures. g/mol How many moles of H3PO4H3PO4 can be produced from one mole of P4P4 ? Hint: You need to look at both reaction (1) and reaction (2). Your answer should...
