Problem 43E

Classify each of the listed properties of isopropyl alcohol (also known as rubbing alcohol) as physical or chemical.

a. colorless                                 b. flammable

c. liquid at room temperature                 d. density = 0.79 g/mL

e. mixes with water

Step-by-Step Solution:
Step 1 of 3

Solution 43E To find out the significant figures, we have to know the rules how to calculate the significant figures. All digits of a measurement including uncertain number are called significant figures. Significant figures = all certain digits + one uncertain digit The rules for determining the significant figures are (i) Zeros between nonzero digits are always significant. For example: 1002 (four significant figures) (ii) Zeros at the beginning of a number are never significant.(0.001, has one significant figures) (iiI) Zeros at the end of a number are significant if the number has a decimal point only.(4.0 has two significant figures) Mass of the object in the balance is 21.427g Here, total number of significant figures are five. This is because, all non zero digits are significant before and after the decimal places.
