Answer 1

To convert from grams (g) to kilograms (kg), we need to divide the value in grams by 1000 since there are 1000 grams in a kilogram.

Let's perform the conversion:

7.4 g ÷ 1000 = 0.0074 kg

To express this value in scientific notation with the correct number of significant figures, we have:

7.4 g = 7.4 × 10^0 g = 7.4 × 10^0 kg = 7.4 × 10^(-3+0) kg = 7.4 × 10^(-3) kg

Therefore, 7.4 g is equal to 7.4 × 10^(-3) kg in scientific notation, with the correct number of significant figures.
