Answer:
Answer: a, b, c, d, e, f. a) 1 significant figure b) 3 significant figures c) 2 significant figures d) 4 significant figures e) 5 significant figures f) 6 significant figures Note that non-integers are rounded to the nearest integer and then count as the number of significant figures. For example, rounding 1.5 to two significant figures would mean one significant figure because it is an integer, not because it is a decimal.
Answer explanation: 26.000 cm = 2.6 x 10^2 cm. 0.800 km = 8 x 10^-3 km. 0.00050 g = 5 x 10^-4 g. 7300 m = 7.3 x 10^2 m. 3 x 10^5 mL = 3000000 ml or 300 L
Step-by-step explanation:
How many significant figures are in each of these measurements?
32.14 cm
4.34 x 10^3 cm
2 g
13000 L
1.007 g/mL
6 mL
0.000005 L
2.7 mL
Answer: a, b and c contain 7 significant figures and the others each have 4 significant figures.
