Answer
(a) 5
(b) 2
(c) 2
(d) 3
(e) 4
(f) 3
Work Step by Step
1. Identify and count the significant zeros:
(a) $11.\underline{00}5 \space g$ : 2
(b) $0.00032 \space m$ : 0
(c) $36000000 \space km$ : 0
(d) $1.8\underline{0} \times 10^4 \space kg$ : 1
(e) $0.825\underline 0 \space L$ : 1
(f) $3\underline{0.0} \space ^{\circ} C$ : 2
2. Sum the number of nonzero digits and significant zeros.
(a) 3 + 2 = 5
(b) 2 + 0 = 2
(c) 2 + 0 = 2
(d) 2 + 1 = 3
(e) 3 + 1 = 4
(f) 1 + 2 = 3
