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

The empirical formula of the following compounds 0.903 g of phosphorus combined with 6.99 g of bromine.
<h3>What is empirical formula?</h3>The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula, S2O2, are two straightforward examples of this idea. As a result, both the sulfur and oxygen compounds sulfur monoxide and disulfur dioxide have the same empirical formula.
<h3>How to find the empirical formula?</h3>Convert the given masses of phosphorus and bromine into moles by multiplying the reciprocal of their molar masses. The molar masses of phosphorus and bromine are 30.97 and 79.90 g/mol, respectively.
Moles phosphorus = 0.903 g phosphorus = 0.0293 mol
Moles bromine 6.99 g bromine=0.0875 mol
The preliminary formula for compound is P0.0293Bro.0875. Divide all the subscripts by the subscript with the smallest value which is 0.0293. The empirical formula is P1.00Br2.99 ≈ P₁Br3 or PBr3
