3 significant figures.
To determine the number of significant figures in the product of 2.8 and 10.5, we look at the number of significant figures in each number. The number 2.8 has 2 significant figures, and 10.5 has 3 significant figures. When multiplying, the result should be reported with the same number of significant figures as the factor with the least significant figures, which is 2. Therefore, the product of 2.8 x 10.5 should be expressed with 2 significant figures.

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.
