4) In a titration of a 100.0mL 1.00M HA weak acid solution with 1.00M NaOH, what is the pH of the solution after the addition of 49.5 mL of NaOH? K_a = 1.80 x 10^-5 for HA. (3 significant figures)

**Remember to calculate the equivalence volume and think about in which region along the titration curve the volume of base falls, region 1, 2, 3, or 4**

5) In a titration of a 100.0mL 1.00M HCl strong acid solution with 1.00M NaOH, what is the pH of the solution after the addition of 30.9 mL of NaOH? (3 significant figures)

**Remember to calculate the equivalence volume and think about in which region along the titration curve the volume of base falls, region 1, 2, 3, or 4**

In solving the following problem :

The local bank pays 4% interest on savings deposits. In a nearby town, the bank pays 1% per quarter. A man who has $3000 to deposit wonders whether the higher interest paid in the nearby town justifies driving there.

1. How much will the man receive after 2 years if he used the local bank? The answer is closest to:

Q2)

What sum of money now is equivalent to $8250 two years hence, if interest is 4% per 6-month period? The answer is closest to:

Hint : 4% per 6 month means semi annual periods so the n does not equal 2 anymore !

The mean cost of domestic airfares in the United States rose to an all-time high of $385 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $105. Use Table 1 in Appendix B.

a. What is the probability that a domestic airfare is $560 or more (to 4 decimals)?

b. What is the probability that a domestic airfare is $250 or less (to 4 decimals)?

c. What if the probability that a domestic airfare is between $300 and $470 (to 4 decimals)?

d. What is the cost for the 2% highest domestic airfares? (rounded to nearest dollar) $ or Select your answer 1. More 2. Less

Skysong Company’s record of transactions concerning part X for the month of April was as follows.

Calculate average-cost per unit. Assume that perpetual inventory records are kept in units only. (Round answer to 4 decimal places, e.g. 2.7682.)

Compute the inventory at April 30 on each of the following bases. Assume that perpetual inventory records are kept in units only. (1) First-in, first-out (FIFO). (2) Last-in, first-out (LIFO). (3) Average-cost. (Round final answers to 0 decimal places, e.g. 6,548.)

If the perpetual inventory record is kept in dollars, and costs are computed at the time of each withdrawal, what amount would be shown as ending inventory under (1) FIFO, (2) LIFO and (3) Average-cost? (Round average cost per unit to 4 decimal places, e.g. 2.7621 and final answers to 0 decimal places, e.g. 6,548.)
