1. The problem states a mass of 150 kilograms. 2. Since no further operation or context is given, the mass is simply 150 kg. 3. To provide more context, if you need to convert this to another unit like grams, you multiply by 1000: $$150 \times 1000 = 150000$$ grams. 4. If you want to find the weight on Earth, multiply by gravity $g = 9.8$ m/s$^2$: $$150 \times 9.8 = 1470$$ newtons (N). Final answer: The mass is $150$ kilograms.
