An 18-karat gold bracelet has a mass of 2.0 ounces. It it is 75% pure gold, what is the total mass in grams of the pure gold?
Her teacher gave her the following formulas:
1g = 16 ounces
1 pound= 454 kg
We easily figured out that there are two parts to the formula and used inverse proportionate ratios to calculate this:
?mass of pure gold.
?mass of pure gold= 2.0 X 1 lb. X 454 kg
16 oz. 1 lb.
We got the answer but, it came out to 0.017 g/cm3, but we have no idea where to go next to get the percentages of the gold to 100%. Could you please give us a few ideas to help us along? Thank you so much!
