Question

c + 2f₂ → cf₄
6.0 mol f₂ are needed during the reaction. what is the mass of the f₂?
molar mass f₂: 38 g/mol
? g f₂

Explanation:

Step1: Recall the formula for mass

The formula to calculate mass is \( \text{Mass} = \text{Moles} \times \text{Molar Mass} \).

Step2: Identify given values

We are given the number of moles of \( F_2 \) as \( 6.0 \, \text{mol} \) and the molar mass of \( F_2 \) as \( 38 \, \text{g/mol} \).

Step3: Calculate the mass

Substitute the values into the formula: \( \text{Mass} = 6.0 \, \text{mol} \times 38 \, \text{g/mol} \).
Calculating this, \( 6.0 \times 38 = 228 \, \text{g} \).

Answer:

\( 228 \)
