Volume of iron shot added = 48.39 ml - 39.99 ml = 8.40 ml
mass = density × volume
= 7.92 g/ml × 8.40 ml
= 66.528 g
≈ 66.5 g
It is 66.53 grams, approx.
It's basically a circle with an added third dimension of height.
Here is the information you are given and a corresponding equation demonstrating the relationship between the given information and the unknown. Vtotal = Vwater + Vsand = 42cm3 Here is the given equation rearranged (by subtracting the volume of water from both sides) to target the unknown information (volume of sand). Vsand = Vtotal - Vwater Plugging in the given info to the equation yields your answer. Vsand = 42 - 20 Vsand = 22cm3
A cylinder is a circle with an added dimension, height. Area of a circle is pi*r^2, and the volume of a cylinder is pi*r^2*h.
A cylinder whose radius is 2cm and height is 8cm has a total surface area of approximately 125.66cm2 {ADDED} To explain that further, the formula is pi*r^2 X h where r is the radius and h the height.
To find the area of a cylinder you need: (π=pi) Therefore the surface area is all of those added together. or simplified Your answer: A=179.4878 Keep in mind that this is the surface area of the top bottom and side, or the total surface area of the geometric object. Be certain the question isn't just being asked of the cylinder wall itself, if that were the case the formula would simply be 2πrh and the answer would then be about 100.5

after 5.63 gm sample of wood metal was added in a 10ml graduated cylinder the new water level is 8.7ml "http://wiki.answers.com/Q/Was_the_water_in_a_cylinder_before_the_sample_was_added" after 5.63 gm sample of wood metal was added in a 10ml graduated cylinder the new water level is 8.7ml "http://wiki.answers.com/Q/Was_the_water_in_a_cylinder_before_the_sample_was_added"
mass = 28.5 g volume = 49.10 ml - 45.50 ml = 3.60 ml density = mass / volume = 28.5 g / 3.60 ml ~= 7.92 g/ml 1 ml = 1 cu cm Therefore density of iron is approx 7.92 g/cm³
Density = mass/volumemass of rock = 250 g - 110 g = 140 gvolume of rock = 37 ml - 30 ml = 7 mldensity of rock = 140 g/7 ml = 20 g/ml
A little hard when you didn't give us the original water level...
No. Density is an intrinsic property and does not depend on the amount or size of the sample. If you are referring to finding the volume of an irregular solid by water displacement, then you will get a very large experimental error if the solid sticks out of the water. The amount of water added to the graduated cylinder initially, must be enough to completely cover the solid, before you place the solid in the cylinder.
Mass of unknown liquid = 142.01 g - 105.56 g = 36.45 gVolume of unknown liquid = 45.5 mldensity = mass/volume = 36.45 g/45.5 mldensity = 0.801 g/ml
Well, that depends on what cylinder you are using. For example, a graduated cylinder is used to measure the volume of a liquid, the measure of a solid by displacement, or for measuring quantities of volumes to be added into a mixture or chemical reaction.
