At a cost of $1600/oz, how much would you have to pay for a solid cubic foot of gold?
Alex777 [14]
<h3>You will pay $ 30876800</h3>

We'll begin by calculating the mass in ounce (oz) of a cube foot (ft³) of gold. This can be obtained as follow:

<h3 />

Density of gold = 19298 oz/ft³

Volume of gold = 1 ft³

<h3>Mass of gold =?</h3>

Density = mass /volume

19298 = mass / 1

<h3>Mass of gold = 19298 oz</h3>

Finally, we shall determine the cost of 19298 oz of gold. This can be obtained as follow:

1 oz = $ 1600

Therefore,

19298 oz = 19298 × 1600

19298 oz = $ 30876800

Therefore, a solid cube foot of gold (i.e 19298 oz) will cost $ 30876800

Which of the following represents the smallest mass? I.) 23 cg II.) 2.3 x 10-3 μg III.) 0.23 mg IV.) 0.23 g V.) 2.3 x 10-2 kg​
jenyasd209 [6]

The smallest mass among the choices is Choice (ii):2.3 x 10-3 μg

This is so because, the prefix μ signifies a factor of 10^-6.

For choice I:

  • 23 cg means 23 centigrams

  • In essence = 0.23grams

For choice II:

  • 2.3 × 10-3 μg means 2.3 × 10-9 grams

For choice III:

  • 0.23 mg means 0.23 × 10-3 grams

For choice IV:

  • 0.23 grams simply means 0.23grams

For choice V:

  • 2.3 × 10-2 kg means 23 grams

Ultimately, Choice II represents the smallest mass.
