Answer

(a) 4 (b) 6 (c) 3 (d) 3 (e) 3 (f) 2

Work Step by Step

1. Identify and count the significant zeros: (a) $2\underline 0.6\underline0 \space mL$ : 2 (b) $1\underline 0 36.48 \space kg$ : 1 (c) $4.\underline{00} \space m$ : 2 (d) $2\underline 0.8 \space ^{\circ} C$ : 1 (e) $6\underline 0 800000 \space g$: 1 (f) $5.\underline 0 \times 10^{-3} \space L$ : 1 2. Sum the number of nonzero digits and significant zeros. (a) 2 + 2 = 4 (b) 5 + 1 = 6 (c) 1 + 2 = 3 (d) 2 + 1 = 3 (e) 2 + 1 = 3 (f) 1 + 1 = 2
