Get started for freeYou are given a liquid. Briefly describe steps you would take to show whether it is a pure substance or a homogeneous mixture.
Convert these to nonscientific notation: (a) \(1.52 \times\) \(10^{4},\) (b) \(7.78 \times 10^{-8}\)
Mercury is the only metal that is a liquid at room temperature. Its density is \(13.6 \mathrm{~g} / \mathrm{mL}\). How many grams of mercury will occupy a volume of \(95.8 \mathrm{~mL} ?\)
Carry out these operations as if they were calculations of experimental results, and express each answer in the correct units and with the correct number of significant figures: (a) \(7.310 \mathrm{~km} \div 5.70 \mathrm{~km}\) (b) \(\left(3.26 \times 10^{-3} \mathrm{mg}\right)-\left(7.88 \times 10^{-5} \mathrm{mg}\right)\) (c) \(\left(4.02 \times 10^{6} \mathrm{dm}\right)+\left(7.74 \times 10^{7} \mathrm{dm}\right)\) (d) \((7.8 \mathrm{~m}-0.34 \mathrm{~m}) /(1.15 \mathrm{~s}+0.82 \mathrm{~s})\)
