,POST LAB QUESTION
A. Units of Measurement
a. Provide the correct conversion units for the following
measurements: 100 Å thickness of cell membrane = 10 nm
1A = 0.1nm
100A x 1A = 100A
100A x 0.1 = 10nm
8 Å diameter membrane pore = 800 pm
1pm = 0.01A
.01 = 800pm
15 g hemoglobin per 100 ml blood =
150mg/ml 15g = 15 x 1000 = 15000mg
15000 mg / 100 ml = 150 mg/ml
100 ml plasma =
0.1L 1000ml = 1L
100/ 1000 = 0.1L
25°C room temperature = 77 °F
0° C = 32°F
Formula = ( °C X 9/5) + 32
= 77°F
98.6°F body temperature = 37 °C
0° C = 32°F
Formula = (32°F - 32) x 5/9 = 0°C
= (98.6°F - 32) x 5/9 = 37°C
b. A powerlifter lifts 500 lb 6 ft off the ground. How much work has he performed?
3000 ft-lb work = 414.9 kg-m work
3000 lb/ft = 1 kg-m / 7.23 lb/ft
= 414.9 kg-m
,How many calories of energy did he used to produce this work? 973 cal
1 kg-m = 2.34385 cal
414.94 x 2.34385 = 973 cal
If he performs this feat 11 times in 1 minute, what is his power output? 746 W
1 Horsepower (HP) = 746 W
, B. Concentration of Solutions
1. How many grams of glucose would you need to make 500 ml of an 8 % solution?
40 g
percentage = (gram solute / volume solution)
x 100 glucose (g) = () x 500
= 40g
2. If 6 g of NaCl is dissolved in 1 L of solution, what percent concentration is prepared?
0.6 %
percentage concentration = 6g / 1000 ml x 100
= 0.6 %
3. How many grams of KCl would you need to make 250 ml of a 0.5 M solution?
9.31 g
M = n/V
0.5 = n/0.25
n = 0.125 mol
Molar mass of KCL= 39 g/mol (K) + 35.5 g/mol (Cl) = 74.5 g/mol.
= (39+35.5) 0.125 mol
= 9.3125 g
= 9.31 g
