In Active Example 3-29 you calculated that you would have to work six weeks to earn enough money to buy a 1082.49 television. You would be working five shifts of four hours each at 9.25/hr. But, alas, when you received your first pay check, you found that exactly 23 of your earnings had been withheld for social security, federal and state income taxes, and workers compensation insurance. Taking these into account, how many weeks will it take to earn the 1082.49?
In the following scenario, identify which of the statements represents a theory, law, or hypothesis. (a) A student exploring the properties of gases proposes that is she decreases the volume of a sample of gas then the pressure exerted by the sample will increase (b) Many scientists over time have conducted similar experiments and have concluded that pressure and volume are inversely proportional. (c) She proposes that the reason this occurs is that if the volume is decreased, more molecules will collide with a given area of the container walls, causing the pressure to be greater.

Orciprenaline(C11H17N03,211.258 g/mol) is a bronchodilatorused in the treatment of asthma.The BP assay for orciprenalinetablets is described below. Read thefollowing information carefully andanswer the questions below.(Record your answers in decimalnotation to the indicated significantfigures OR decimal places)ASSAY - 20 tablets weighing 2.597 gwere crushed to a powder. Aportion of the crushed powder(0.5456 g) was shaken with 50 mL of0.1 M HI, the mixture was filteredand made up to 100 mL. 10 mL ofthis solution was further diluted to100 mL with 0.1 M HCI. Themeasured absorbance of thediluted solution at 276 nm was0.582.
