Chemistry Lesson: Steemit Edition Problem Set 1

1.) How many significant figures are there in:
a. 12.014
5
23
b. 1.30 x 10 3
c. 0.0005
1
d. 1402
4

2.) We know that the sun is 5777 K is what is the temperature of the sun in °F? (Use Factor
Labeling)

5 °𝐶

3.) You were involved in a rather unusual gambling ring, run by a bookie with some pretty odd
quirks (he’s a real sicko). You’ve been racking up the debts (unfortunately in this hypothetical
scenario you are a bad gambler). The bookie comes to collect and tells you that you owe him a
humpback whales weight in quarters, and if you don’t pay up he’s going to cut off both of your
ears (I told you he’s quite sick). How much money would that be in USD? (The average weight of
a humpback whale is 66,000 Lbs, One US quarter weighs 5.67 grams, any other conversion
factors you need are available in the constants and conversions link at the bottom of the post in
the references section)

Uh Oh! You’d better post a few more blogs on Steemit to pay off this debt 
