CHM 131 McGuirk PRINT FULL NAME: Section Number: 1. Circle the numbers written with incorrect scientific notation. a. 31.5 x 105 d. 8.912 x 10 b. .2 x 102 e. 0,000681 x 10 c. 5.73 x 10 f. 9.01 x 10 2. For the two numbers you circled above in question two, rewrite the numbers with the correct scientific notation. Incorrect example #1 Incorrect example #2: 3. Using the following formula: Tr-1.8Tc+32 rearange the equation to solve for Tc (Show all work) 4. Using the following formula below rearange the equation to solve for Ti. (Show all work)Explanation / Answer
Ans 1
Incorrect scientific notation
a.
31.5 x 10-5
e.
0.000681 x 107
Ans 2
Correct scientific notation
31.5 x 10-5 = 3.15 x 10-4
0.000681 x 107 = 6.810 x 103
Ans 3
TF = 1.8 TC + 32
Step - 1
TF - 32 = 1.8 TC
STEP 2
TC = (TF - 32)/1.8
ANS 4
P1V1/T1 = P2V2/T2
Cross multiplication method
P1V1T2 = P2V2T1
T1 = (P1V1T2)/(P2V2)
