To convert liters to grams, you need to know the density of the substance you are measuring. For water, the density is approximately 1 gram per milliliter (or 1000 grams per liter).
Since 1.5 liters of water weighs about 1500 grams (1.5 liters x 1000 grams/liter), we can calculate:
- 25% of 1.5 liters is calculated by multiplying 1.5 liters by 0.25:
1.5 liters x 0.25 = 0.375 liters
Now, to find the mass in grams:
- 0.375 liters x 1000 grams/liter = 375 grams
Therefore, 25% of 1.5 liters is equal to 375 grams.
