CHEM II Math Review...

Description

Lab 1 – Chem 2 Math The purpose of this exercise is: - Practice some common math operations you may see in Chem 2 - Identify areas of weakness and make a plan to remedy them You must show your work neatly to receive full credit. You may use whatever resources you need (except other people). Please answer the following questions:

1)

log X = Y

X = ??

2)

ln 63 – ln 9 + ln 5 = ??

3)

( a14 / a6 )3 x ( b4 / a4 )3 = ??

4)

log (8 – X) = log 3X

5)

log 2700A = B/C + log 27A B = ??

6)

ln (K + b) = - 14yz

X = ??

K = ??

7)

(4.0 x 1023) x (3.0 x 10 -14) (6.0 x 1017) / (3.0 x 10 -10)

=

8) The sun is 93,000,000 miles from earth. If light travels at 3.0 x 108 m/sec, how many minutes does it take light from the sun to reach earth?

9) A very strong man lifted a 760 lb barbell off the floor. If this is the maximum that he can lift, calculate if he could he lift a cubic foot of mercury off the floor? (Hg density = 13.6 g/cm3)

10) The roof area of a large building measures 2.24 acres (an acre is 43,560 square feet). During a rainstorm one evening, 0.65 inches of rain accumulated on the roof. Assuming the density of the rain that fell was 1.00 gram per cubic centimeter, what is the weight, in pounds, of the rain on top of the building?...
