Convert 2.54 moles of CaCl, to liters.
1 answer:
2.54 moles of CaCl occupies 56.89 liters volume
Explanation:
- Each mole of any gas occupies 22.4 liters volume at STP.
- STP is defined as the standard temperature and pressure and those standard values are zero degree and one atmospherics pressure
- 22.4 liters is a constant number as Avogadro's number which is nothing but 6.022*
.
- Hence, to convert 2.54 moles just multiply it with 22.4 L
- That is, 22.4*2.54= 56.89 L
- So, 2.54 moles of CaCl occupies 56.89 L volume space

Answer: Option (C) is the correct answer.
Explanation:
When chemical composition of a substance is not changing in a chemical reaction then it is known as a physical change.
For example, when water change state, from ice to steam then it means solid state is changing into gaseous state.
Therefore, it is a physical change.
And, a reaction which causes change in chemical composition is known as a chemical change.
For example,
Thus, we can conclude that we can see water change state, from ice to steam. This is a physical change in matter.
