Question

determine the number of significant figures in each of the following measurements: part 1 of 4 (a) 4867 mi; significant figure(s). part 2 of 4 (b) 0.0000003 cm; significant figure(s). part 3 of 4 (c) 60,104 ton; significant figure(s). part 4 of 4 (d) 2901 g; significant figure(s).

Explanation:

Step1: Non - zero digits are significant

For 4867 mi, all four non - zero digits are significant.

Step2: Leading zeros are not significant

For 0.0000003 cm, only the non - zero digit 3 is significant.

Step3: Zeros between non - zero digits are significant

For 60,104 ton, the zeros between 6 and 1, and 1 and 4 are significant, so all five digits are significant.

Step4: Non - zero digits are significant

For 2901 g, all four digits are significant as the zero is between non - zero digits.

Answer:

(a) 4
(b) 1
(c) 5
(d) 4
