Introductory Chemistry 5
Determine the number of moles of \(\mathrm{H}\) in each sample. (a) \(4.67 \mathrm{~mol} \mathrm{H}_{2} \mathrm{O}\) (b) \(8.39 \mathrm{~mol} \mathrm{NH}_{3}\) (c) \(0.117 \mathrm{~mol} \mathrm{~N}_{2} \mathrm{H}_{4}\) (d) \(35.8 \operatorname{mol} \mathrm{C}_{10} \mathrm{H}_{22}\)

Mathematical Statistics with Applications 7
A biologist has hypothesized that high concentrations of actinomycin D inhibit RNA synthesis in cells and thereby inhibit the production of proteins. An experiment conducted to test this theory compared the RNA synthesis in cells treated with two concentrations of actinomycin D: 0.6 and 0.7 microgram
