The price of gold on April 15,2000 was $282/t. oz. How much did 100.0cm^3 of gold cost that day if 1.00 t. oz=28.4 grams?

price ($) Au = $ 19183.94

Explanation:

april 15,2000:

∴ price Au = $ 282/t. oz

∴ 1.00 t. oz = 28.4 g

∴ V Au = 100.0 cm³ ⇒ price ($) = ?

∴ δ Au = 19.32 g/cm³

⇒ mass Au = (100.0 cm³) * (19.32 g/cm³)

⇒ m Au = 1932 g

⇒ price ($) = (1932 g Au) * (1.00 t. oz/28.4 g Au) * ($ 282/t. oz)

⇒ price ($) = $ 19183.94
