1) You want to find the volume of a metal sphere (Note: the formula for the volume of a sphere is V = 4㎡ , where r is the radius of the sphere). You measure the radius of the sphere to be r-2.18 cm, with a measurement uncertainty of + 0.02 cm. What is the volume of the sphere as well as the corresponding uncertainty of the calculated volume?

1. An experiment is performed in the lab, where the mass and the volume of an object are measured to determine its density. Two completely different valid methods are used. Each experimental method to measure the density is performed, two considerable sets of data are taken on each and the results are compared. The results of the density measurement by each method should be ... a. dependent on the mass and the volume of the object b. completely different, because...

3. In extremely high-precision gravimetric titrations, the uncertainty in formula mass of the primary standard could contribute to the uncertainty of the result. Express the formula mass of potassium hydrogen phthalate (CgH5O4K) with its proper absolute uncertainty using the atomic masses given in the inside cover of our text. 4. The error in measuring the diameter of a sphere is ± 0.02 cm. What is the volume of the sphere and its absolute error for a diameter of 3.15 cm?

You have two objects made of the same substance. Object 1 is a cube with a mass of 465.5 g. You measure the side of the cube using a ruler and find it to be 3.17 cm. Object 2 is a sphere with a mass of 232.8 g. You find the volume of the sphere using water displacement. The volume of the water in a graduated cylinder initially is 120.0 mL, and when the sphere is added the new volume...

1. Newton's Universal Law of Gravitation can be written as F = G*M1*M2/r^2 where M1 and M2 are masses of objects in kilograms (kg), r is the distance between the objects in meters (m), and F is the magnitude of the force the objects exert on each other in units of kilograms times meters per second squared (kg*m/s^2). Determine the units of the universal gravitational constant, G. In your answer, use only units of kg, m, and s. Write any...

To measure the density of a rectangular object, an experimenter measures the object's volume and mass. The volume is given by the formula V = LWH, where L is the length, W is the width, and H is the height. The density is given by p = m/V, where m is the object's mass. If the measurement of the mass is uncertain by 2%, and each of L, W and H is uncertain by 4%, what is the uncertainty, in...

To determine the volume of a sphere, you measure its diameter using a ruler an obtain a value of 15.2 mm for the diameter. Using this diameter, you convert the diameter to units of centimeters by dividing the radius by 10 mm/cm and then you divide the diameter by 2 to obtain the radius (r). You then use the equation V = 4/3rr to obtain the volume of the sphere. To determine the mass, you measure the mass on a...
