The "lead" in your pencil is actually graphite, a form of carbon. If the 0.7mm diameter "lead" was actually made out of lead and was 4.411 cm long, what would be it's resistance in Q at 82 degrees C? (lead resistivity p = 22 x 10^-8 Qm at 20 C and a = -39 x 10^-4 C^-1)

Chalcopyrite is among the most common varieties of copper ore. Assuming chalcopyrite is 34.4% copper by mass (34.4 grams copper per 100. grams of ore), how many kilograms of chalcopyrite would be needed to smelt 30.0 kilograms of pure copper?
A student finds that 24.96 g of water at 24.9 C(density=0.9971 g/cm3) is required to completly fill an empty flask. The water is removed and completely dried; granular solid copper weighing 51.24g is then added to the flask. With the copper present in the flask, it was determined that 19.24 g of water was required to fill the remaining space in the flask completly 1.) volume of the empty flask 2.) volume of the copper 3.) density of the copper
to make a tablet of aspirin, it requires 249 mg of salicylic acid. if the chemist purchased 9.0 x 10^-3 OZ of salicylic acid, are these enough to make one table of aspirin?
A student weighed their penny (mass = 2.499 g) and followed the same experimental procedure you did in the lab. They found that the penny contained 0.0980 g of copper, or, 3.92%. Estimate the thickness of the copper coating with the following formula. From the US Mint website: the diameter of a penny is 19.05 mm and the thickness is 1.52 mm. The density of copper is 8.96 g/cm3.

Assuming that the copper and lead are pure, determine the relative amounts of each kind of BB. The density of copper is 8.96 g/cm ^ 3 . The density of lead is 11.4 g/cm ^ 3
A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 11.10 g.L-¹. The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.30 g⋅L¯¹. Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Be sure your answer has the correct number of significant digits.
