Carry out each of the following conversions. Reference the SI prefixes table for additional information. Report your answers using scientific notation 7.4. g to kg Be sure your answer has the correct number of significant figures.
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.
