Given that 0.5 grams =500mg, how many mg are in 50g

Solution:
1. Given:
- Conversion: 0.5 grams = 500 milligrams

2. To find the conversion factor:
- 0.5 grams \times \frac{1000 \text{ mg}}{{1 \text{ g}}} = 500 \text{ mg}
- Thus, 1 gram = 1000 milligrams

3. Determine the number of milligrams in 50 grams:
- 50 \text{ g} \times 1000 \frac{\text{mg}}{\text{g}} = 50000 \text{ mg}

4. Therefore, there are 50000 milligrams in 50 grams.
