How do you calculate the mass in kilograms of 3.99 liters of acetic acid. The density of this substance is 1.05 g/mL.

.0042 kg

mass = volume x density

mass = 3,990 mL x 1.05 mL = ? g.
Then divide by 1000 to convert to kg.

To calculate the mass in kilograms of 3.99 liters of acetic acid, follow these steps:

Step 1: Convert liters to milliliters.
Since there are 1000 mL in 1 liter, multiply 3.99 liters by 1000 to get the volume in milliliters.
3.99 liters x 1000 mL/liter = 3990 mL

Step 2: Calculate the mass in grams using the density.
The density of acetic acid is given as 1.05 g/mL. Multiply this density by the volume in milliliters to get the mass in grams.
1.05 g/mL x 3990 mL = 4189.5 grams

Step 3: Convert grams to kilograms.
Since there are 1000 grams in 1 kilogram, divide the mass in grams by 1000 to get the mass in kilograms.
4189.5 grams ÷ 1000 = 4.1895 kilograms

Therefore, the mass in kilograms of 3.99 liters of acetic acid is approximately 4.1895 kilograms.

To calculate the mass of a substance, you need to know its density and volume. Here's how you can determine the mass of acetic acid:

Step 1: Convert the volume of acetic acid to liters to match the density unit. In this case, the volume is already given in liters, so no conversion is needed.

Step 2: Multiply the volume (in liters) by the density (in grams per milliliter) to get the mass in grams. The formula is:

Mass (in grams) = Volume (in liters) x Density (in g/mL)

Mass (in grams) = 3.99 liters x 1.05 g/mL

Step 3: Convert the mass from grams to kilograms. Since there are 1000 grams in a kilogram, you divide the mass (in grams) by 1000.

Mass (in kilograms) = Mass (in grams) / 1000

Solving the equation:

Mass (in grams) = 3.99 liters x 1.05 g/mL = 4.1895 grams

Mass (in kilograms) = 4.1895 grams / 1000 = 0.0041895 kilograms

Therefore, the mass of 3.99 liters of acetic acid is approximately 0.0042 kilograms (rounded to four decimal places).
