Question

Bismuth oxide reacts with carbon to form bismuth metal:

Answer 1

(a) 3.33 mol Bi

Explanation:

Step 1: Convert 283 g to moles

Bi Molar Mass - 208.98 g/mol × 2 = 417.98 g/mol

O Molar Mass - 16.00 g/mol × 3 = 48.00 g/mol

283 g Bi₂O₃ ÷ 465.98 g/mol = 0.0607 mol Bi₂O₃

Step 2: Find the conversion from Bi₂O₃ to Bi

1 mole of Bi₂O₃ equals 2 moles of Bi

Step 3: Use Dimensional Analysis

1.66316 mol  ·   = 3.32632 mol Bi

3.32632 mol Bi ≈ 3.33 mol Bi

What is bismuth oxide used for?

Bismuth oxides have been considered as an interesting material because of their dielectric properties and have been used for applications such as optical coatings, metal-insulator-semiconductor capacitors and microwave-integrated circuits.
