MgCl₂ is an empirical formula for magnesium chloride.
<h3>What is empirical formula?</h3>
The empirical formula of a chemical compound in chemistry is the simplest whole number ratio of atoms in a compound. Two simple instances of this concept are the empirical formulas of sulfur monoxide (SO) and disulfur dioxide (S2O2). As a result, the empirical formulas for the sulfur and oxygen compounds sulfur monoxide and disulfur dioxide are the same. However, they do not share the same molecular formulas, which indicate the number of atoms in each molecule of a chemical compound.
An empirical formula does not mention the arrangement or number of atoms. It is typical for many macromolecules, including ionic compounds like calcium chloride and silicon dioxide (SiO2) (CaCl2).

Answer: 1.314 ppm
explain: thats what someone said
A gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C. Details about temperature can be found below.
<h3>How to calculate temperature?</h3>
The temperature of a gas can be calculated using the following formula:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- R = gas law constant
- T = temperature
0.755 × 4.31 = 1 × 0.0821 × T
3.25 = 0.0821T
T = 3.25 ÷ 0.0821
T = 39.58°C
Therefore, a gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C.
