An empty 250 mL beaker has a mass of 60 g when 100 mL of oil is added to the beaker the total mass is 140 g the density of the oil is approximately?
To find the density of the oil, we first determine the mass of the oil. The total mass of the beaker with the oil is 140 g, and the mass of the empty beaker is 60 g, so the mass of the oil is 140 g - 60 g = 80 g. Density is calculated as mass divided by volume, so the density of the oil is 80 g / 100 mL = 0.8 g/mL.

How many milligrams are in 1.2ml?
That completely depends on the density of the substance in the 1.2 ml. If the 1.2 ml is empty, then there are no milligrams in it at all.
How do you measure the volume of an irregular object?
Place it in a graduated cylinder (or any other metered container), completely submerge the object, and record the amount of water displaced. ---------------------------------------------------------------------------------------- Place an empty beaker onto a second larger catch pan. Be sure that your catch pan will hold water without leaking, and make sure it is large enough to catch ALL of the water that will spill out of the beaker. Fill a beaker until you can see the meniscus above the rim of the container. CAREFULLY lower your irregular object into the beaker with water allowing the beaker to over flow into the catch pan. Once you have your object submerged in the beaker, remove the beaker from the catch pan. Let the little bit of water adhered to the exterior of the beaker drip into the catch pan for a few seconds to make your measurement as accurate as possible. Using a graduated cylinder, measure the volume of water that has over flowed into your catch pan. The volume of this water will be very close to the volume of your irregular object.
Why do steel ships float if the density of iron is much greater than the density of water?
The ships are not made of solid iron. They contain much empty space where the cargo and or passengers go. So the overall density of a ship: its TOTAL mass divided by its TOTAL volume is less than that of water.
How does the density of a crushed metal can compare to the density of the metal can before it was crushed?
The crushed can will have a density that is quite a bit higher than the density of the can before it was crushed. Imagine a box of empty aluminum beverage cans. It won't weigh much. If those same cans are crushed, they will weigh the same, but take up a lot less space. The density of the cans can be increased by crushing them. The cans might be said to have a low bulk density before being crushed.
How many 200 liter drum make 1 metric ton?
Too many unknown variables to answer ! What size are the drums, are the drums empty, if not - what is the density of the substance they're filled with...
An empty beaker has a mass of 115 g After some water is added to the beaker the mass is 147 g What is the mass of the water?
32 g
What is the mass of 250 mL beaker filled with 100 mL of water?
Well, darling, a 250 mL beaker filled with 100 mL of water would have a mass of approximately 100 grams. Water has a density of 1 g/mL, so 100 mL would weigh 100 grams. The beaker itself doesn't add any weight, unless you're counting the weight of your expectations.
Should we measure the mass of a beaker before measuring a chemical or powder inside the beaker?
You can do that or you can zero balance the scale with the empty beaker on it before adding the substance to be measured to the beaker.
How do you measure weight and volume of water not quite filling a 50ml beaker?
It is necessary to know the mass of the empty beaker.
What is the mass of an empty 200ml beaker?
Change 200mL into decimal.
Will an electrical circuit with a battery be completed by two copper electrodes in an empty beaker when the beaker is filled with distilled water?
No, distiled water will not conduct electricity.
Mass of a empty 100ml beaker?
The mass of an empty 100ml beaker can vary depending on the material it is made of. For a typical glass beaker, the mass is usually around 100-150 grams. However, for a plastic beaker, the mass may be lighter, around 20-50 grams. It is important to use a balance to measure the exact mass of the specific beaker you are using in a scientific experiment.
Suppose you want to find the mass of a powdered solid in a small beaker. What two measurements must you make in order to obtain an accurate measurement of the solid's mass?
Measure the mass of the beaker including the powdered solid. Then empty the beaker, make sure ALL traces of the powder have been removed and measure the mass of the empty beaker. The difference between the two measure is the measure of the powdered solid.
What is the density of an empty water bottle?
400
How do you calculate the mass of water?
u2/cm/g3 * * * * * I have no idea about the above answer, but it does not appear to answer the question. The best way to find the mass of a given quantity of water is to use a balance to find the mass of an empty container. Then pour the water into the container and measure their combined mass. The difference between the two is the mass of the water.
What is the the weight of a 250 ml beaker in milligrams?
250 grams because water density is the same for ML to GRAMS. No if it was filled with water to 250 ml the water would weigh 250 grams. The beaker would weigh whatever, depending on the thickness of the glass.
What is the mass of a 400ml beaker?
Approximately 1 gram/millilitre for the water, but not all small beakers of water have the same mass. In fact, it's much more likely the masses differ than are the same. Are you trying to fake a lab exercise or is this just a silly question?
