What is the equation for calculating the volume cube, a cylinder and a sphere? List these of a below and explain the variables. If you don't know these equations refer to your book or do a Google search. cube sphere cylinder 2. Calculate the density ofa liquid if30.0 mLofthe liquid has...
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...
Calculate the density of a solid substance if a cube measuring 2.55 cm on one side has a mass of 125 g. Answer: ? g/cm^3 Calculate the mass of a cube of the same substance measuring 8.35 cm on one side. Answer: ? g Please show all steps with explanation! Thankyou
A cube made of platinum (Pt) has an edge length of 1.50 cm. The density of Pt is 21.45 g/cm3. (a) Calculate the number of Pt atoms in the cube. (b)Atoms are spherical in shape. Therefore, the Pt atoms in the cube cannot fill all the available space. If only 74.0 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. The mass of a single Pt atom...
in C++ use Inheritance for the following Shape Circle Sphere Cylinder Rectangle Square Cube You must define one class for each shape. And, use public inheritance when deriving from base classes. Circle int r; void area(); void perimeter(); void volume(); //No volume for circle Sphere int r; void area();//Sphere surface area= 4 × pi × radius2 void perimeter(); //No perimeter for Sphere void volume();//Sphere volume= 4/3 × pi × radius2 Cylinder int r, height; void area();// Cylinder surface area=perimeter of...
Find the density of an element by mass of 20.0 gram and shape of a cylinder which has a diameter of 1.0cm and length of 5.0 cm? Find your answer by g/cm3
Save An Question 14 1 points Determine the density of a regular solid if it weighs 12 3749 g and length, width and height are 1242 cm, 1.232 cm, and 1 243 cm respectively. Write the answer up to the correct number of significant figures
Calculate the surface area and volume of a rectangular solid measuring 43mm in length, 12mm in width, and 19mm in height (report your answer in cm square and cm cube). The mass of this block is 8.4g. What is it's density and will it sink or float in water?
Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the...
Atoms are spherical in shape. Therefore, the Pt atoms in the cube cannot fill all the available space. If only 74.0 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. The mass of a single Pt atom is 3.240 times 10^-22 g. [The volume of a sphere of radius r is (4/3) pi r^3. The volume of a cube is l^3, where l is the length of...
