mass of empty flask plus stopper 36.765 g

mass of stoppered flask plus water 65.264 g

Temperature 24.8 C

calculate the volume?

need help please

mass H2O = 65.264-36.765 = ?

Look up the density of water at 24.8 C.
Then mass = volume x density.
You know mass and density, substitute and solve for volume.

To calculate the volume of the water in the flask, you need to know the density of water at the given temperature (24.8°C).

The density of water varies depending on the temperature. At 4°C, water has a density of 1.00 g/mL. As the temperature increases, the density of water decreases.

First, let's find the mass of water in the flask:

Mass of stoppered flask plus water = 65.264 g
Mass of empty flask plus stopper = 36.765 g

Mass of water = Mass of stoppered flask plus water - Mass of empty flask plus stopper
= 65.264 g - 36.765 g
= 28.499 g

Now we need to find the volume of the water. We can use the formula:

Volume = Mass / Density

However, since the density of water changes with temperature, we need to adjust the density at the given temperature of 24.8°C.

The density of water at 24.8°C is 0.9957 g/mL.

Volume of water = Mass of water / Density of water
= 28.499 g / 0.9957 g/mL
≈ 28.68 mL

So, the volume of water in the flask is approximately 28.68 mL.

To calculate the volume of the water in the flask, you need to use the principle of water displacement. The volume can be calculated by subtracting the initial volume of the flask from the final volume with the stoppered flask and water.

Here are the steps to calculate the volume:

1. Subtract the mass of the empty flask plus the stopper from the mass of the stoppered flask plus water to find the mass of the water.

Mass of Water = Mass of Stoppered Flask + Water - Mass of Empty Flask + Stopper

Mass of Water = 65.264 g - 36.765 g

2. Convert the mass of water to grams to milliliters.
Since the density of water at 24.8 °C is approximately 1 g/mL, the mass of the water is equivalent to the volume.

Volume of Water = Mass of Water

Volume of Water = 65.264 g - 36.765 g

3. Calculate the density of water at 24.8 °C using the following formula:
Density = Mass / Volume

4. Use the density to calculate the volume of water.
Volume = Mass of Water / Density

Since the density of water at 24.8 °C is approximately 1 g/mL, the volume of water is the same as the mass of water.

Volume of Water = 65.264 g - 36.765 g

Therefore, the volume of water in the flask is equal to the difference in masses, which is 28.499 grams or 28.499 milliliters.
