Convert 2.54 moles of cacl, to liters.

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 pressure22.4 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 LSo, 2.54 moles of CaCl occupies 56.89 L volume space

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).
