The weight of the beaker with 40mL of water will depend on the density of the water and the material of the beaker. Water has a density of 1g/mL, so the weight can be calculated by multiplying the density by the volume. The weight of the beaker itself will need to be accounted for as well.
It depends what beaker your talking about.
The weight of 40ml of oil will vary depending on the type of oil. On average, 40ml of oil weighs about 36 grams.
The weight of 40ml of a substance depends on its density. To find out the weight in grams, you would need to know the density of the substance in question. Different substances have different densities, which will affect the conversion from volume (ml) to weight (grams).
To make a 2% solution from a 25% solution, you need to dilute it. Let x ml be the amount of water needed. Using the equation for mass balance: 0.25(40) = 0.02(40 + x), solve for x to find that x = 875 ml of water needs to be added.
1 cm^3 of water weighs approximately 1 gram.
It depends what beaker your talking about.
How much a beaker weighs depends on the size of the beaker and the thickness of the glass. A small beaker might weigh a few ounces while a large beaker will weigh several times that.
40mL of plain water weighs about 1.41 ounces or 40 grams.
The weight of 40ml of oil will vary depending on the type of oil. On average, 40ml of oil weighs about 36 grams.
basically 38 divided by 40 which equals 0.95 grams
First you weigh it, then you put it in a beaker with a known amount ow water in it. By noting how much the volume of water increases you get the volume of the magnetite. Now you got all you need to determine the density.
40 ounces of water is approximately 1,133.981 ml
which water?
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?
it is the same weigh.
The easiest way is to place the object in a graduated beaker of water, and see how much the water rises when you put it in. Archimedes Principle says that the volume of the object is the same as the water displaced from the beaker.
To much.
