Explanation / Answer
I am solving the Q7 as per Chegg guidelines, post multiple questions to get the remaining answers
Q7)
1 ounce = 28.3495 grams
Cost of gold in grams = $1320/28.3495 = $46.5166/gram
Density of Gold = 1.10 gm/mL
For $55700, the amount of gold in grams will be 55700/46.5166 = 1196.262 grams
Density = Mass/Volume
Volume = Mass/Density = 1196.262/1.10 = 1087.51 mL
1.75 * 10^(-9) * Mass = 1196.262
Mass = 1196.262/1.75 = 6.8357 * 10^(11) grams of sea water
Volume of sea water = 6.214 * 10^(11) L = 1.641 * 10^(11) gallon
