calculate the mass in kilograms of 3.99 liters of acetic acid. the density if 1.05g/ml.

mass = volume x density

Convert L to mL and substitute the numbers. Solve for mass in grams and convert to kg.

0.004185

To calculate the mass in kilograms of acetic acid, you need to use the given density and volume of the liquid. Here's the step-by-step explanation of how to solve it:

Step 1: Convert the given density from grams per milliliter (g/mL) to grams per liter (g/L). Since 1 mL is equal to 0.001 L, we can multiply the given density by 0.001 to convert it:
Density = 1.05 g/mL * 0.001 L/mL = 0.00105 g/L

Step 2: Use the volume of 3.99 liters and the converted density to calculate the mass:
Mass = Density * Volume
Mass = 0.00105 g/L * 3.99 L = 0.0041945 g

Step 3: Convert the mass from grams to kilograms by dividing it by 1000 (since there are 1000 grams in a kilogram).
Mass in kilograms = 0.0041945 g / 1000 = 0.0041945 kg

Therefore, the mass of 3.99 liters of acetic acid is approximately 0.0041945 kilograms.
