Why is copper plumbing used in our homes but not aluminum plumbing? 4. The average human needs 2.0 mg of copper ions, Cu2+, per day in their diet. This is how many copper ions? 5. Copper is extracted from the ore, chalcopyrite, CuFeS2. How many kilograms of a 0.862% chalcopyrite ore will be necessary to produce 1.00 kg of pure copper? The percentage of copper in chalcopyrite needs to be known to work this problem. 111

» Significant Figure Rules 01 >> 02 >> 03 >> 04 >> 05 >> All nonzero digits are significant. Zeros that appear between other nonzero digits are always significant. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that locks a decimal point are not significant. ▬▬▬ 美銀銀時 ☐☐ Right-end zeros in a number with a decimal point are significant. This is true whether the zeros occur before or ofter the decimal point. 237 has three significant figures. 1.897 has four significant figures. 39,004 has five significant figures. 5.02 has three significant figures. 0.008 has one significant figure. 0.000416 has three significant figures. 140 has two significant figures. 75,210 has four significant figures. 620.0 has four significant figures. 19.000 has five significant figures.
