What is the density of an object with volume of 20cm3 and a mass of 40g?
The density of the object is 2 g/cm3. This is calculated by dividing the mass (40g) by the volume (20cm3).
What is the weight of a 40kg object?
The weight of a 40kg object on Earth would be approximately 392.4 Newtons. Weight is calculated by multiplying the mass of an object by the acceleration due to gravity (9.81 m/s^2).
How much work is done to lift 40kg of bricks to a height of 10m?
The work done to lift 40kg of bricks to a height of 10m can be calculated using the formula: Work = Force x Distance. The force required to lift the bricks is equal to the weight, which is mass x gravity (40kg x 9.8m/s^2). Plug these values into the formula to find the work done.
What is the weight of an oject that has a mass of 40kg?
The weight of an object is the force exerted on it due to gravity. On Earth, the weight of an object can be calculated by multiplying its mass by the acceleration due to gravity (9.8 m/s^2). Therefore, an object with a mass of 40 kg would weigh approximately 392 N on Earth.
What is 40g in kilogram?
40g is equal to 0.04 kilograms.
Is a anker 40g 40kg?
40kg
What is the density of an object with volume of 20cm3 and a mass of 40g?
The density of the object is 2 g/cm3. This is calculated by dividing the mass (40g) by the volume (20cm3).
What is the density of an unknown solid with a mass of 40g and a volume of 2ml?
The density of the unknown solid is 20 g/ml. This is calculated by dividing the mass (40g) by the volume (2ml).
How many moles of calcium are in a sample of 40g?
To find the number of moles in 40g of calcium, we need to divide the mass by the molar mass of calcium (40.08 g/mol). So 40g / 40.08 g/mol = approximately 1 mole of calcium.
What is your weight and mass on earth if you way 40 kg?
40kg of mass, 400 (approx) N of weight.
What is the mass of 1 mole of calcium atom?
40g
If 40g of sea water contains 2g of salt how would you calculate the mass of the water and the mass of the salt?
The mass of the water would be 40g - 2g = 38g. The mass of the salt would be 2g.
What is the mass of 40g of sugar water?
The mass of the sugar water would still be 40g. When a solute, like sugar, is dissolved in a solvent, like water, the mass of the solution remains the same as the individual components do not change their mass through dissolution.
What is the density of an object with a volume of 20cm3and a mass of 40g?
Density = 2 g/cm3
What mass of hydrogen is needed to react with 40g of copper oxide CuO plus H2-- Cu plus H20?
To find the mass of hydrogen needed to react with 40g of copper oxide (CuO), first calculate the molar mass of CuO. Then, use stoichiometry to determine the moles of CuO present in 40g. From the balanced chemical equation CuO + H2 -> Cu + H2O, you can determine the mole ratio between CuO and H2. Finally, use the molar mass of hydrogen to calculate the mass of hydrogen needed to react.
What is 40kg in stone?
40kg = 6.29892178 stone
How do you calculate the weight in newtons of mass 40kg?
You multiply the mass by the gravity. Normal Earth gravity is about 9.8 (in meters/second2, or the equivalent newton/kilogram).
