(a) There are five significant figures in this measurement. We can write this measurement in scientific notation: $1.0544\times 10^{-4}~kg$ (b) There are four significant figures in this measurement. We can write this measurement in scientific notation: $5.800\times 10^{-3}~cm$ (c) There could be three, four, five, or six significant figures in this measurement. We can write this measurement in scientific notation: $6.02\times 10^{5}~s$
(a) $0.000~105~44~kg$ There are five significant figures in this measurement. We can write this measurement in scientific notation: $1.0544\times 10^{-4}~kg$ (b) $0.005~800~cm$ There are four significant figures in this measurement. We can write this measurement in scientific notation: $5.800\times 10^{-3}~cm$ (c) $602~000~s$ When zeros are written to the left of the decimal point, it is not clear whether they are significant figures or not. There could be three, four, five, or six significant figures in this measurement. Let's assume there are three significant figures. We can write this measurement in scientific notation: $6.02\times 10^{5}~s$
