Final answer:
To convert mL to grams, use the formula: mass (g) = volume (mL) x density (g/mL)
Step-by-step explanation:
To convert milliliters (mL) to grams (g), you need to know the density of the substance you are working with. The density is usually given in grams per milliliter (g/mL) or kilograms per liter (kg/L). Once you have the density, you can use the formula:
mass (g) = volume (mL) x density (g/mL)
For example, if the density of a substance is 2 g/mL and you have 10 mL, the mass would be:
mass (g) = 10 mL x 2 g/mL = 20 g
