To determine the number of significant figures in the product of 0.1400, 6.02, and (10^{23}), we need to identify the significant figures in each number. The number 0.1400 has four significant figures, 6.02 has three significant figures, and (10^{23}) has one significant figure (as it is a power of ten). The product will have the same number of significant figures as the term with the least significant figures, which is 6.02 with three significant figures. Therefore, the final product will have three significant figures.
The numbers 12, 10, 20.5, and 1.00 have different significant figures: 12 and 10 each have two significant figures, 20.5 has three significant figures, and 1.00 has four significant figures. When ordered from least to greatest number of significant figures, the sequence is 12 (2), 10 (2), 20.5 (3), and 1.00 (4). Thus, the order from least to greatest is: 12, 10, 20.5, 1.00.
29.05 to 3 significant figures
