Final answer:
To convert 843 g/mL to g/L, multiply by 1000 to get 843000 g/L. However, the original density value is extremely high and possibly a typo. The conversion to g/L should be done while considering the significant figures of the original measurement.
Step-by-step explanation:
To convert 843 grams per milliliter (g/mL) to grams per liter (g/L), you simply need to multiply by 1000, since there are 1000 milliliters in a liter. The correct conversion would be:
843 g/mL × 1000 mL/L = 843000 g/L
Note that the original number provided likely contains a typographical error, as 843 g/mL is an unusually high density that isn't typical for most substances under normal conditions. However, the conversion process described here is valid for converting any g/mL value to g/L.
When dealing only with significant figures, keep in mind that your final answer should reflect the same level of precision as the original data provided. For example, if you have a density that has only two significant figures, like 1.3 g/L, you would round off the final answer to two significant figures as well.
