Answer:
Explanation:
To convert from moles to grams, we must use the molar mass (also known as the gram formula mass).
First, look up the molar masses of the elements in the formula.
- C: 12.011 g/mol
- H: 1.008 g/mol
- O: 15.999 g/mol
Next, multiply by the subscript, because it tells us the number of atoms of each element in the formula.
- C₉: 4(12.011 g/mol)= 108.099 g/mol
- H₈: 8(1.008 g/mol)= 8.064 g/mol
- O₄: 4(15.999 g/mol)= 63.996 g/mol
Add the values.
- 108.099 + 8.064+63.996=180.159 g/mol
Use this molar mass as a ratio.
Multiply by the given number of moles, 0.40
The units moles of aspirin cancel.
The original number of moles has 2 sig figs (4 and 0), so answer must have the same. For the number we calculated, it is the ones place. The 0 in the tenth place tells us to leave the 2.
There is one simple way to determine between solids, liquids, and gases. Are you able to move the substance? And if you are, how does it move? If it takes on the shape of its new container, it is a liquid. For example, if you pour water from a cup into a bowl, it will fill the bowl, not stay in the same shape as it was in the cup. However, if you put a marble in a cup and then pour the marble into the bowl, it will remain the same shape, and is therefore a solid. If you move a gas into a container, and the container is not sealed, it will not remain in the same shape.

From the calculations and the statement of the general gas equation, the volume of the gas becomes 28.8 L

What are gas laws?</h3>
The gas laws are used to show the relationship between the variables in problems that has to do with gases.
In this case, we have to apply the general gas law as follows;
P1V1/T1 = P2V2/T2
P1V1T2 = P2V2T1
V2 = * 22L * 1.5 atm * 273K/313K * 1 atm
V2 = 28.8 L
