Textbook Question
Chapter 1, Problem 2ASA
Finding the density of an unknown liquid.
Having obtained the volume of the flask, the student emptied the flask, dried it, and filled it with an unknown liquid whose density she wished to determine. The mass of the stoppered flask when completely filled with liquid was
a. First we need to find the mass of the liquid by measuring the difference:
b. Since the volume of the liquid equals that of the flask, we know both the mass and volume of the liquid and can easily find its density using the equation in lb. Make the calculation.

2) There are many forms of cancer, all of which involve abnormal cell growth. The growth and
production of cells, called cell proliferation, is known to involve an enzyme called protein
farnesyltransferase (PFTase). It is thought that inhibitors pf PFTase may be useful as anticancer
drugs. The following molecule showed moderate activity as a potential PFTase inhibitor. Draw all
stereoisomers of this compound.

- The fire releases 2.80 x 107 Joules of heat energy for each liter of oil burned. The water starts out at 24.5 °C, raising the water's temperature up to 100 °C, and then raises the temperature of the resulting steam up to 325 °C. How many liters of water will be needed to absorb the heat from the fire in this way, for each 1.0 liter of crude oil burned? 4186 J/(kg°C) = heat of water 2020 J/(kg°C) = heat of steam 2,256,000 (i.e. 2.256 x 106) J/kg = latent heat of vaporization for water (at the boiling point of 100 °C).arrow_forward6 Which of the following are likely to be significant resonance structures of a resonance hybrid?
