± Convert between Units of Concentration

Chemists often use molarity M, in moles/liter, to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume. Volume markings for most laboratory glassware are calibrated for room temperature, about 20∘C.

Fortunately, there are several other ways of expressing concentration that do not involve volume and are therefore temperature independent.

A 2.400×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by dissolving a sample of NaCl in water and then bringing the volume up to 1.000 L. It was determined that the volume of water needed to do this was 999.4 mL . The density of water at 20.0∘C is 0.9982 g/mL.

Respond to ONE of the following scenarios. Identify and discuss the relevant legal issues and discuss them fully. Specifically state what you think the outcome will be and why. In Questions #1, be sure to include the applicable general rule(s) as well as any exceptions and whether they apply.

1. Jim Bowie owns a lot in Starr County and wants to build a house according to a certain set of plans and specifications. He solicits bids from three building contractors as follows: George Kimbell bids $ 175,000; Green Jameson bids $170,000; and, Davy Crockett bids $ 166,000. Bowie accepts Crockett’s bid and construction begins. A month into the work, Crockett advises Bowie that due to an unexpected rise in fuel and materials costs, he will need $ 15,000 more to complete the project. Bowie raises a fuss, but after discussing the situation with the out-bid contractors who indicate that they cannot finish the contract for less, he agrees. When the house is finished, he refuses to pay the extra money. Discuss whether Bowie is legally required to pay the additional amount.

Exercise 7-15 Manufacturing: Direct materials, direct labor, and overhead budgets LO P1

MCO Leather Goods manufactures leather purses. Each purse requires 3 pounds of direct materials at a cost of $4 per pound and 0.7 direct labor hours at a rate of $10 per hour. Variable manufacturing overhead is charged at a rate of $2 per direct labor hour. Fixed manufacturing overhead is $11,000 per month. The company’s policy is to end each month with direct materials inventory equal to 20% of the next month’s materials requirement. At the end of August the company had 4,580 pounds of direct materials in inventory. The company’s production budget reports the following.

Production Budget September October November
Units to be produced 4,800 7,200 6,500
