It depends what beaker your talking about.
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
the lump of sugar will slowly dissolve and undergo osmosis, if you stir or swirl the beaker it this will happen much faster
I guess none. Why? The given is that the water is boiling -- it is turning into vapor.
About 42 pounds.
40mL of plain water weighs about 1.41 ounces or 40 grams.
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.
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?
it is the same weigh.
1500 litres of water weigh 1500 kg
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.
