The given compound has 3 carbon atoms, so in 1 mole of that compound, there will be 3 moles of carbon atoms.
Mass of each mole of carbon atoms = 12 g
For 3 mole carbon atoms, it will be 12 × 3 = 36 grams

Changes in matter occur every day. There are two types of ways matter can be altered; physically and chemically. Physical changes do not change the composition of the matter while chemical changes occur when one or more substances turn into a completely new substance. Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing the composition of the subject. Descriptive words that would help to identify a substance’s physical property include hard, soft, brittle, flexible, heavy, and light just to name a few. Let’s say you’re eating, throughout the day your stomach starts to growl that is what happens when your stomach is digesting your food. Digestion is an example of chemical change. Chemical change happens every day and more than half the time we don’t realize it whether it’s metal starting to rust, or our food starting to rot. Physical change can happen when your popsicle starts to melt, or your water starting starting to boil. These are examples of physical change.

Use the ideal gas equation PV=nRT. You can compare before and after using P1V1/n1T1=P2V2/n2T2. Since the number of moles remains constant you can disregard moles from the equation and use pressure, volume and temp. Make sure your pressure is converted to atmospheres, your volume is in liters, and your temperature is in kelvins.
the nebular theory states that the solar systems developing <u><em>rotations </em></u>revolve around sun. it is located in the milky-way. revolving around the <u><em>sun</em></u>, with <u><em>gravity</em></u> pulling it, an interstellar cloud of dust and gas, is formed. (i.e. the nebula that we are speaking)
this formation is a<u><em> protostar</em></u>. the idea in the theory states that the <u><em>nebula</em></u> has flattened into a <u><em>disk</em></u> called the "protoplanetary disk"; and over time, the debreis eventually formed this disk. (i.e. creating the milky-way)
hopefully this helped, thank you!! :D
