Answer:
Not possible
Explanation:
To determine the mass in grams of 6.55 × 10²⁵ molecules of Cl₂, we need to use the concept of molar mass and Avogadro's number.
1. Find the molar mass of Cl₂:
The molar mass of an element is the mass of one mole of that element. Cl₂ represents a molecule of chlorine gas, which consists of two chlorine atoms. The atomic mass of chlorine (Cl) is approximately 35.45 grams/mole. Therefore, the molar mass of Cl₂ is 35.45 grams/mole × 2 = 70.90 grams/mole.
2. Use Avogadro's number to convert the number of molecules to moles:
Avogadro's number is 6.022 × 10²³ molecules/mole. By dividing the given number of molecules (6.55 × 10²⁵) by Avogadro's number, we can find the number of moles.
6.55 × 10²⁵ molecules ÷ 6.022 × 10²³ molecules/mole = 108.67 moles.
3. Calculate the mass in grams:
Multiply the number of moles by the molar mass to find the mass in grams.
108.67 moles × 70.90 grams/mole ≈ 7712.56 grams.
Therefore, the mass in grams of 6.55 × 10²⁵ molecules of Cl₂ is approximately 7712.56 grams.
So, none of the options A, B, C, or D provided in the question match the correct answer.
