Question

Approximately how many ounces of gold were mined in that country that year?

a) 1,500,000
b) 1,200,000
c) 1,000,000
d) 1,800,000

Answer 1

The volume of 1 troy ounce of pure gold, given a mass of 31.103 grams and a density of 19.32 g/cm3, is approximately 1.61 cubic centimeters.

Step-by-step explanation:

The student is asking for the volume of 1 troy ounce of pure gold. One troy ounce of gold is equal to 31.103 grams. To find the volume, we need the density of gold, which is approximately 19.32 g/cm3. The formula to calculate volume is mass divided by density (V = m/ρ). Using this formula:

V = 31.103g / 19.32g/cm3

V ≈ 1.61 cm3

The volume of 1 troy ounce of pure gold is therefore approximately 1.61 cubic centimeters.
