A 150-G Sample of a Hydrocarbon Is Placed in a Balloon

question 26

Short Answer

A 15.0-g sample of a hydrocarbon is placed in a balloon at 1.00 atm and 25°C, and the volume of the balloon is 12.2 L. The hydrocarbon is 79.89% carbon and 20.11% hydrogen by mass. Determine the molecular formula of the hydrocarbon.

Definitions:

Saltatory Conduction

The transmission of a neural impulse along a myelinated neuron; ion activity at one node depolarizes the next node along the axon.

Voltage-Activated

Pertains to ion channels in cell membranes that open or close in response to changes in membrane potential.

Action Potential

A rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane, due to the movement of ions in and out of the neuron.

Voltage-Gated

Refers to a type of ion channel that opens or closes in response to changes in the electrical potential across a cell membrane.
