WebFor a given a density ρ, the relationship between mass and volume is V = 4 3 π r 3 m = ρ V = 4 3 π ρ r 3 The bottom equation gives you your relations. Of the two variables you are interested in, mass ( m) and radius ( r ), the solutions in terms of one another are: m = 4 3 π ρ r 3 r = 3 m 4 π ρ 3 Be careful with units! WebTo find density: Ex. If the mass of an object is 35 grams and it takes up 7 cm3 of space, calculate the density Set up your density problems like this: Given: Mass = 35 grams Unknown: Density (g/ cm3) Volume = 7 cm3 Formula: D = M / V Solution: D = 35g/7 cm3 D = 5 g/cm3. Let’s try some density problems together Work on these problems with your

Density = Mass ÷ Volume Multiply both sides of the equation by volume to get: Density x Volume = Mass or Mass = Density x Volume Now, plug in the numbers to solve the problem: Mass = 3.2 kg/m 3 x 1.25 m 3 If you see the units won't cancel out, then you know you did something wrong. If that happens, … See more As an example of a simple problem, find the mass of a piece of metal that has a volume of 1.25 m3 and a density of 3.2 kg/m3. First, you should notice both the volume and the density use the volume of cubic meters. That … See more The density of goldis 19.3 grams per cubic centimeter. What is the mass of a bar of gold in kilograms that measures 6 inches x 4 inches x 2 inches? See more Density is equal to the mass divided by the volume. D = m/V where D = density m = mass V = volume We have the density and enough information to find the volume in the problem. All that remains is to find the mass. Multiply both … See more WebThe weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. For an object in free fall, so that gravity is the only force acting on it, then the expression for weight follows from Newton's second law.
