∙ 6y agoVolume 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'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
The mass of water added is 110 g minus the initial empty cylinder mass. The mass of the rock is the total mass of 250 g minus the mass of the water and empty graduated cylinder. The density of the rock can then be calculated using the mass of the rock and its volume (37 mL - 30 mL).
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"
A little hard when you didn't give us the original water level...
The mass of the graduated cylinder was measured at the beginning of the experiment to determine the empty weight of the container before any other substances were added to it. This allowed for the accurate calculation of the mass of the liquid poured into the cylinder by subtracting the initial empty mass from the total mass measured after the liquid was added.
A graduated cylinder is used to accurately measure the volume of a liquid. It is commonly used in laboratories for tasks such as making precise measurements for experiments, determining the concentration of solutions, and ensuring accurate amounts of liquid are added during procedures.
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.
The increase in mass is 45g (245g - 200g) due to the added liquid. This corresponds to a volume of 26ml because 1g/ml is the density of water (and marketed) liquids. Therefore, the density of the liquid is 45g / 26ml = 1.73 g/ml.
The volume of the stone is equal to the difference in water levels before and after the stone was added, so the volume of the stone is 85mL - 50mL = 35mL. To find the density, divide the mass of the stone (75.0g) by its volume (35mL). The density of the stone is 75.0g / 35mL ≈ 2.14 g/mL.
The volume of the object is the difference in water level before and after the object is added, which is 10 ml (30 ml - 20 ml). The density of the object is mass divided by volume, so 2g / 10 ml = 0.2 g/ml. Therefore, the density of the object is 0.2 g/ml.
No, the density of the liquid will not change based on whether parts of the solid stick out of the water. Density is solely determined by the mass and volume of the liquid present, regardless of the shape of the solid object in the liquid.
Measuring the volume of pennies by their displacement requires that only water actually displaced by the pennies is measured. Unless the water was at the very top of the cylinder both before and after the pennies are added, splashed water will make the measurement invalid.Because surface tension forms a curved surface at the top of the water, it is advisable to have the cylinder only partly filled, and measure the level at the same part of the curved water surface both before and after the pennies are added. This will improve the accuracy of measurement.
