How did the discovery that mass is a form of energy resolve the debate over Earths age?
by know of initial mass of the earth and mass of the earth in this time we can find mass decay of the earth and by the formula of E=MC2 we can find the energy of the earth and when we have the energy by formula E=E0e(it) we can find t that is the time
How do you find the mass of an object based on the displaced water?
To find the mass of an object based on the displaced water, you can make use of Archimedes' principle. Measure the volume of the water displaced by the object, and then multiply it by the density of water (usually 1 g/mL). This will give you the mass of the object.
What is the formula to find force when mass and acceleration are known?
F = m AMultiply (mass) times (acceleration). The product is (force).
How do you determine relative density of butter?
When you find the relative density of butter, use the formula for density = mass/volume. First find the mass, or weight of the butter, and then divide the butter by its volume.
Mass is 145g and velocity is 25ms Find the answer using kinetic energy formula?
Kinetic energy is 0.45 joules using the formula Ek = ½ x mv2
Compare the densities of cans of cola with the density of water?
The formula for calculating density is D=m/V. Density equals mass divided by volume. Calculate the volume of the cans, and then find the mass. Then find the mass of the coke and water in the cans. Subtract the mass of the cans so you're left with the masses of the coke and water. Put the masses and volumes into the formula.
How would you find out how much 12.4 moles of water weigh?
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
What is the formula to find Calories per gram?
(difference in water) x (mass of water) x (specific heat of water) x (1kc/ 10000c)
Why is the term molecular mass applied to water but the term formula mass applied to aluminum chloride?
molecular formula is referred to water because they are covalent compounds while formula mass for aluminum chloride because they are ionic compounds
How does one determine a molecule formula from the empirical formula?
The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula.
What is the formula to finding density of water?
mass/volume
What is the formula for finding the mass of an object?
To find the volume of an object use the formula v=dm where Volume=Density x Mass To find the mass of an object use the formula m=dv where Mass=Density x Volume
What formula to find mass in a triangular prism?
Mass = Density x Volume
What is the formula to find mass?
density x volume
How does on determine a molecular formula from the empirical formula?
molar mass over grams of elementThe above answer is somewhat correct. In order to find the molecular formula when given the empirical formula, you must first find the molar mass of the empirical formula.MOLAR MASS# atoms element A x Atomic Mass element A (Periodic Table) = mass A# atoms element B x atomic mass element B (periodic table) = mass B... etc.Add up all of the mass values found above and you have the molar mass.Then, after you have found the empirical formula's molar mass, you divide the molar mass of the molecular formula by the empirical formula's molar mass (solving for n).MOLECULAR FORMULA EQUATION: N (Empirical formula) (read as N times empirical formula) where:N = Molar mass substance---- Molar Mass emp. form.
How can you find the mass of water when you have a balance?
okk first find like a tube thingy and find the mass of it on the balance and write it down somewhere then put the water in the tubee and find the mass and write it downn when your donee subtract the mass of the tube from the mass of the tube with water in it and your answerr is the mass of the water ***make sure the tube has no water in it or ANYTHING because it could change the mass okk first find like a tube thingy and find the mass of it on the balance and write it down somewhere then put the water in the tubee and find the mass and write it downn when your donee subtract the mass of the tube from the mass of the tube with water in it and your answerr is the mass of the water ***make sure the tube has no water in it or ANYTHING because it could change the mass
How would you find the mass of 250 militers of water?
how would you find the mass of 250 mL of water
