Asample of cl 2 cl2 gas has a volume of 25.0 l 25.0 l at a pressure of 1.50 atm and a temperature of 23 ∘ c. 23 ∘c. what volume, in liters, will the gas occupy at 3.50 atm and 261 ∘ c? 261 ∘c? assume ideal behavior.

19.33L

Explanation:

To calculate the volume it will occupy, we simply use the general gas equation formula.

P1V1/T1 = P2V2/T2

Given P1 = 1.50 atm , V1 = 25.0L , T1 = 23 degrees Celsius = 23 + 273 = 296K

P2 = 3.50 atm , V2 = ? , T2 = 261 + 273 = 534K

Rearranging the equation:

P1V1T2/P2T1 = V2

Substituting the values:

(1.5 * 25 * 534 )/(3.5 * 296) = V2

V2 = 19.33L

3. Identify the elements and calculate the number of atoms in a chemical formula

All the capital letter in a chemical formula are the elements and if they have a number next to it that indicates the amount of atoms in the chemical formula if there is no number then there is 1.

We breathe out CO2 when we exhale. The chemical formula for carbon dioxide shows that carbon dioxide contains atoms of carbon (C) and oxygen (O).
