What is the mass (in kg) of 3.2 L of Br2?
Br can be a liquid or a gas at normal temps and pressure. You have to know more.
To find the mass of 3.2 L of Br2, you need to know the density of Br2. The density of a substance tells you how much mass is present in a given volume. In this case, you need to convert from liters to kilograms using the density of Br2.
Here are the steps to find the mass:
1. Find the density of Br2: The density of Br2 at a given temperature and pressure can be found in a reference source, such as a chemistry handbook or online database. Let's assume the density of Br2 is 3.12 g/mL.
2. Convert liters to milliliters: Since density is typically expressed in grams per milliliter (g/mL), you need to convert 3.2 L to milliliters (mL). There are 1000 mL in a liter, so 3.2 L is equal to 3200 mL.
3. Calculate the mass: To find the mass, you need to multiply the volume in milliliters (mL) by the density in grams per milliliter (g/mL): Mass = Volume × Density.
Mass = 3200 mL × 3.12 g/mL.
4. Convert grams to kilograms: Since the question asks for the mass in kilograms, you need to convert the mass from grams to kilograms by dividing it by 1000: Mass (in kg) = Mass (in g) ÷ 1000.
Mass (in kg) = (3200 mL × 3.12 g/mL) ÷ 1000.
Calculating this expression will give you the mass of 3.2 L of Br2 in kilograms.
