Answer:
2.29 moles of SF₆ contain 334.5 g SF₆
Explanation:
Given data:
Mass of SF₆ = ?
Number of moles of SF₆ = 2.29 mol
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of SF₆ = 32.065 + (19)×6
Molar mass of SF₆ = 146.06 g/mol
Now we will put the values in formula.
Mass = 2.29 mol × 146.06 g/mol
Mass = 334.5 g
2.29 moles of SF₆ contain 334.5 g SF₆ .
