A trisubstituted cyclohexane compound is given below in its chair conformation. Draw the corresponding planar (overhead) representation, using wedge-and-dash bonds to indicate the substituent positions. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons). Be sure that both wedge/dash bonds are drawn on the outside of the ring, or else the stereochemistry may be interpreted as square planar.
A 16.4-L sample of gas at STP is heated to 55°C at 605 torr. What is the new volume?
What would be the percent by mass of NaI solution prepared by dissolving 95 g NaI in 450 g water?
