To find the total mass in grams, we need to convert all the given measurements to grams and then sum them up.
1. **Convert kilograms to grams**: Since 1 kilogram is equal to 1000 grams, we convert 1.03 kg as follows:
- 1.03 kg = 1.03 × 1000 g = 1030 g
2. **Grams are already in grams**: 1105 g remains the same.
3. **Convert milligrams to grams**: There are 1000 milligrams in a gram, so to convert 1075000 mg to grams, we do:
- 1075000 mg = 1075000 ÷ 1000 g = 1075 g
4. **Now add all the converted values together**:
- 1030 g (from 1.03 kg) + 1105 g + 1075 g = 3210 g
Therefore, the total mass is 3210 grams.
