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
