Answer:
1233.68 g
Step-by-step explanation:
Given:
The weights are
1.21 kg
546 mg
23.14 g
Here,
the units of all the weights given are not uniform, also the options are provided in grams
Therefore, we will first convert all the weights in the uniform unit i.e in grams
thus,
we have
1.21 kg = 1210 g
546 mg = 0.546 g
23.14 g
hence,
the total mass = 1210 g + 0.546 g + 23.14 g = 1233.686 ≈ 1233.68 g
Hence, the correct answer is option 4. 1233.68 g
