1. Convert 845.3 to exponential form and explain your answer.
2. Convert 3.21 x 10 to ordinary form and explain your answer.
-5
1. Convert 845.3 = larger than 1 = positive exponent, move decimal 2 places
= 8.453 x 10 2
2. Convert 3.21 x 10-5 = negative exponent = smaller than 1, move decimal 5
places = 0.0000321
QUIZ# 2

Using the following information, do the conversions shown below, showing all
work:
1 ft = 12 inches 1 pound = 16 oz 1 gallon = 4 quarts
1 mile = 5280 feet 1 ton = 2000 pounds 1 quart = 2 pints
kilo (= 1000) milli (= 1/1000) deci centi (=
1/100) (= 1/10)
1. 24.6 grams = ? kg
,Introduction To General, Organic, And Biological Chemistry With Lab
2. 6.3 ft = ? inches
1. 24.6 grams x 1 kg / 1000 g = 0.0246 kg
2. 6.3 ft x 12 in / 1 ft = 75.6 inches
please always use the correct units in your final answer

Be sure to show the correct number of significant figures in each calculation.
1. Show the calculation of the mass of a 18.6 ml sample of freon with
density of 1.49 g/ml
2. Show the calculation of the density of crude oil if 26.3 g occupies 30.5 ml.
1. M = D x V = 1.49 x 18.6 = 27.7 g
2. D = M / V = 26..5 = 0.862 g/ml
