Final answer:
To solve for 355.8 g + 0.736 kg, we first convert 0.736 kg to grams, getting 736 g. Adding 355.8 g to 736 g gives 1091.8 g, but rounding to four significant figures, as dictated by the least precise measurement, the answer is 1092 g.
Step-by-step explanation:
To solve 355.8 g + 0.736 kg using the correct number of significant figures, first convert kilograms to grams. Since there are 1000 grams in a kilogram, 0.736 kg is equivalent to 736 g (0.736 kg x 1000 g/kg). Now, add the two measurements:
355.8 g + 736 g = 1091.8 g
However, we need to consider the significant figures. The least precise measurement, 355.8 g, has four significant figures after the decimal place. Therefore, our final answer must also have four significant figures: 1092 g (since adding 355.8 g and 736 g resulted in 1091.8 g, rounding to four significant figures gives us 1092 g).
