What is the Mass of 3.81 mol of ph3?, Explain it

 

[kumarrakesh]

To find the mass of 3.81 mol of PH₃ (phosphine), multiply the molar mass of PH₃ by the number of moles. The molar mass of PH₃ is approximately 34.00 g/mol.
Mass = 3.81 mol × 34.00 g/mol = 129.54 g.
Example: 1 mol PH₃ = 34 g; 3.81 mol = 129.54 g.

Use this formula and find the mass of 3.81 mol of PH₃

Mass = Moles × Molar Mass

The molar mass of PH₃ is approximately 33.997 g/mol.

So,
Mass = 3.81 mol × 33.997 g/mol = 129.52 g

Therefore, the mass of 3.81 mol of PH₃ is 129.52 grams.

To find the mass of 3.81 mol of PH₃, multiply the moles by its molar mass (34 g/mol):
3.81 × 34 = 129.54 grams.
So, the mass is 129.54 grams.

To find the mass of 3.81 mol of PH₃, multiply the moles by its molar mass (34 g/mol):
3.81 × 34 = 129.54 grams.
So, the mass is 129.54 grams.

This is the correct answer. But I wanted to calculate by myself also to revise this

Mass = Moles × Molar Mass

• Molar mass of PH₃ = 30.97 (P) + 3×1.01 (H) = 34.00 g/mol
• Mass = 3.81 mol × 34.00 g/mol = 129.54 g

Answer: The mass of 3.81 mol of PH₃ is 129.54 grams.

Multiplying the molar mass of PH₃ by the number of moles yields the mass of 3.81 mol of PH₃ (phosphine). PH₃ has a molar mass of about 34.00 g/mol.
3.81 mol × 34.00 g/mol = 129.54 g is the mass.
Example: 1 mol PH₃ = 34 g; 3.81 mol = 129.54 g.
