Find the molecular formula of the alkane represented in the mass spectrum. A mass spectrum. The peak at mass 100 has an 8% relative abundance. THe peak with mass 85 has a 40% abundance. The peak at 71 has a 3% abundance. The peak at 57 has a 30% abundance. The peak at mass 43 has a 100% abundance. The peak at mass 29 has an 18% abundance. molecular formula:C_{n}H_{x}CnHx Replace the subscript letters with numbers. Formatting counts.

Malik formed a hypothesis that an increase in atmospheric oxygen levels by 10% would cause red-legged grasshoppers to grow larger than normal. suppose that malik performs an experiment to test his hypothesis. which of these actions would represent a scientific mistake in his experiment? a. he experiments on live grasshoppers instead of preserved ones. b. he focuses on red-legged grasshoppers instead of all kinds of grasshoppers. c. he varies the nitrogen and carbon dioxide levels in the air from one trial to the next. d. he conducts the experiment in a controlled lab setting with a lab partner. e. he measures the mass and length of his specimens at the start of each trial.
