Put a container of known volume on a scale, and tare it. Then fill the container exactly to the full mark with the liquid, and record the weight. Divide the weight by the volume to get the density. The fact that it is volatile brings several considerations. If it is so volatile that some has evaporated by the time you weigh it, then it may be necessary to cap the container. Be sure to tare with the container and cap. Also, if it is a toxic volatile liquid, you may need to work in a fume hood.
One method to find the density of a volatile liquid is to use a pycnometer, which is a glass container with a precise volume. First, weigh the empty pycnometer, then add a known volume of the volatile liquid and reweigh. The difference in weight can be used to calculate the density of the volatile liquid.

Method to obtain density of liquid?
To obtain the density of a liquid, you would need to measure its mass and volume. The density is then calculated by dividing the mass of the liquid by its volume. Typically, this is done using a balance to measure mass and a graduated cylinder to measure volume.
How would you find the density of a lump of sodium that is about 10 grams?
The volume must be determined; try the method of liquid displacement using an anhydrous mineral oil.
Would decreasing the amount of liquid to determine density change the outcome?
No, the amount of a liquid is volume. Density is independent of volume.
How much is 200 g of liquid?
The volume of 200 g of liquid would depend on the density of the liquid. For water, which has a density of approximately 1 g/mL, 200 g of water would be equivalent to 200 mL.
Would you expect to change a liquid's density?
The temperature of the fluid
How would the density be affected if some of the volatile liquid was evaporated between getting the volume and the mass?
The density increase.
What is the physical property of chloroform at room temperature?
Chloroform is a colorless, volatile liquid at room temperature with a sweet odor. It has a boiling point of around 61°C and a density greater than water.

Oil would be considered a nonviolatile liquid while gasoline would be considered volatile?
Volatile simply means it evaporates easily. Gasoline evaporates; it's the evaporating gas that burns, not the liquid. Oil doesn't evaporate easily, so it isn't volatile.

Would decreasing the amount of liquid to determine density change the outcome?
No, the amount of a liquid is volume. Density is independent of volume.
Explain how can you find the density of an unknown liquid if you have all of the laboratory equipment you need?
To find the density of an unknown liquid, you would first measure the mass of a known volume of the liquid using a balance. Then, you would measure the volume of the liquid using a graduated cylinder. Finally, divide the mass by the volume to calculate the density of the unknown liquid.
An alternative procedure for determining the density of a liquid would be to pipet a sample of the liquid into a weighed flask then reweigh the flask to determine the mass of liquid transferred?
This alternative procedure would allow you to indirectly measure the density of the liquid by calculating the mass of a known volume that was transferred. By dividing the mass by the volume, you can obtain the density of the liquid without directly measuring it through the traditional method of dividing mass by volume. This method can be efficient for liquids that are difficult to measure using traditional methods due to their properties.
Would an object float at 3.684 density?
It isn't clear what units you are using, what liquid you are placing it in, and whether that is the density of the object or of the liquid. The general rule is that an object will float if it has less density than the liquid in which it is placed.
How much is 200 g of liquid?
The volume of 200 g of liquid would depend on the density of the liquid. For water, which has a density of approximately 1 g/mL, 200 g of water would be equivalent to 200 mL.

1 milliliter of liquid is what amount of milligrams?
The amount of milligrams in 1 milliliter of liquid would depend on the density of the liquid. You would need to know the density of the specific substance to convert milliliters to milligrams.
