For each of the following pairs of aqueous solutions (all are at 300 K, unless otherwise stated), circle the one that has a higher concentration of solute:

1. 1.75 M NaCl or 1.75 m NaCl

2. 1.0% by mass KI or 1.0% by mass KBr

3. a saturated solution of n-butanol (CH3(CH2)2(CH2OH) or a saturated solution of n-decanol (CH3(CH2)8CH2OH)

4. a saturated solution of O2 at 298 K or a saturated solution of O2 at 358 K

5. a saturated solution of He under 1 atm of He or a saturated solution of Xe under 1 atm of Xe

**It would be very very helpful if you can provide an explanation for each one**

How would you prepare the following solutions? Unless stated otherwise, assume that the solvent is purified water and that you will dissolve the solute in a lesser amount of solvent and then “bring the solution to volume”. Show your math and use proper units. CuSO4 FW 159.61 NaCl FW 58.44 CaCl FW 111.0 Na2SO4. 10H2O FW 322.04 11. 250 ml 1 mM CuSO4 12. 500 ml 0.25M NaCl 13. 100 ml 20mM CaCl 14. 10 ml 1 M Na2SO4 15....

Assume all data is normally distributed unless otherwise stated. Please show all steps of the work. The use of both alcohol and tobacco by high school seniors has declined in the last 30 years. Alcohol use is down from 36.7 to 20.4%, and the use of cigarettes by high school seniors has decreased from 68.2 to 43.1%. A random sample of 300 high school seniors from a large region indicated that 82% had NOT consumed any alcohol during the 30...

Note: In this chapter and in all succeeding work throughout the course, unless instructed otherwise, calculate hourly rates and overtime rates as follows: 1. Carry the hourly rate and the overtime rate to 3 decimal places and then round off to 2 decimal places (round the hourly rate to 2 decimal places before multiplying by one and one-half to determine the overtime rate). 2. If the third decimal place is 5 or more, round to the next higher cent. 3....

Assume all data is normally distributed unless otherwise stated. 1) The U.S. Bureau of Labor and Statistics reported that a person between the ages of 18 and 34 has had an average of 9.2 jobs. To see if this average is correct, a researcher selected a random sample of 9 workers between the ages of 18 and 34 and asked how many different places they had worked. At α = 0.05 test the U.S. Bureau of Labor and Statistics claim....

Bond Valuation All bonds have a $1,000 face or par value unless otherwise stated. kc is the coupon rate and kdis the market cost of debt. A $1,000 par value bond sells for $1,216. It matures in 20 years, has a 14 percent coupon, pays interest semiannually, and can be called in 5 years at a price of $1,100. You think it is likely that interest rates will either remain at current levels or else decline over the next 5...
