Hi there!
We can use the following conversions to solve:
Total mass --> amount of mols --> amount of atoms (Avogadro's number)
Begin by calculating the amount of boron trifluoride in 3.61 grams:
3.61 g * (1 mol BF₃ / 67.8 g) ≈ 0.0532 mol BF₃
Use avogadro's number to convert:
0.0532 mol * 6.02× 10²³atoms / 1 mol = 3.203 × 10²² atoms
This is an incomplete question, here is a complete question.
Phosphorus trifluoride is formed from its elements.
How many grams of fluorine are needed to react with 6.20 g of phosphorus?
Answer : The mass of needed are, 11.4 grams.
Explanation : Given,
Mass of = 6.20 g
Molar mass of = 124 g/mol
Molar mass of = 38 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical equation is:
From the balanced reaction we conclude that
As, 1 mole of react with 6 moles of
So, 0.05 moles of react with
moles of
Now we have to calculate the mass of
Therefore, the mass of needed are, 11.4 grams.
