Final answer:
To find the mass of 216 liters of Cl₂ in grams, convert liters to moles using the molar volume, then moles to grams using the molar mass of Cl₂, which results in 684.056 grams of Cl₂.
Step-by-step explanation:
To calculate the mass in grams of 216 liters of Cl2 (chlorine gas), we need to use the molar mass of Cl2. First, we need to convert liters to moles and then moles to grams using the molar mass of Cl2.
The molar volume of a gas at standard temperature and pressure (STP) is 22.4 liters, so you would first convert the liters of Cl2 to moles:
216 liters Cl2 × (1 mole Cl2 / 22.4 liters Cl2) = 9.64 moles Cl2
Then, convert the moles of Cl2 to grams using the molar mass of Cl2:
9.64 moles Cl2 × (70.90 grams Cl2 / 1 mole Cl2) = 684.056 grams Cl2
Therefore, you have 684.056 grams of Cl2.
