The 50g one does have the greater density. This is because density is defined as mass divided by volume.
I took the liberty of changing the density to 5g/cm3 since 5g would be a mass quantity, and the volume to 10cm3, since 10cm would be a length quantity. density = mass/volume mass = density x volume = 5g/cm3 x 10cm3 = 50g
Density= Mass/Volume = .183kg/50cm3= .00366 kg / m^3 the above solution is wrong because you have to get the units right density = mass/volume = kg/m^3 = 1000g/1000000cm^3 density = 0.183/0.00005 = 3660Kg/m^3
for the same volume of both, 5 grams is less dense. Your question shows that you do not understand what Density means. If you want to compare densities of different substances, you must say what the substances WEIGH, and also say what the VOLUME is, of each of them. DENSITY is always expressed in gram/cc (gram per cubic centimetre.). A cube which measures exactly 1cm on all of it's 12 edges, has a volume of exactly 1cubic cm. EXAMPLE of density:- The Density of Aluminium is about 3gm/cc. The density of Steel is about 8 gm/cc. Scientists always measure density by finding the weight of a substance which occupies a volume of 1 cubic cm. I have a booklet which lists the density of every commonly used metal, and rubber and timber. Different timbers have different densities. Timber density can be as low as 0.2gm/cc and as high as 2gm/cc. Always remember that the density of pure WATER is exactly 1gm/cc. A commonly used term is Relative Density, which means the ratio of a substance density compared to WATER. So, you can see that the Relative Density of Aluminium is simply 3, because it's density is 3 times as much as the density of the most common substance on earth(which never changes no matter where it comes from, but it must be PURE Water.) I hope that helps you understand how to talk about Density.
kilo- means 1,000 1,000 / 50 = 20 Answer: twenty 50g weights
Density = Mass/Volume = 50/(4*4*4) = 50/64 = 0.78125 grams per cm3.
density = mass/volume = 50g/8cm^3 = 6.25 g/cm^3
-- Use the length of the cube's side to calculate its volume. -- Divide the cube's mass by its volume. The quotient is its density. The density is 6.25 g/cm3 . Now that you know the answer, you can fill in the missing steps, and learn something at the same time. Is that cool or what !
A 30ml solution with a mass of 45g has a density of 45/30 or 1.5 g/ml, while a 40ml solution with a mass of 50g has a density of 50/40, or 1.25 g/ml. The 30ml solution with a mass of 45g has a higher density.
(50g)/(15g/cm3)=3.333...cm3 or 3 1/3 cm3
Density = Mass/Volume = 50g/12.5mL = 4 g per mL
density = mass/volume = 50g/4.5mL = 11g/mL
Volume = mass/volume = 500g/10cm3 = 50g/cm3
The 50g one does have the greater density. This is because density is defined as mass divided by volume.
You don't need density to find mass. In a lot of question you need to find density with the given mass and volume. But to find density you would use a triple beam balance. To find volume you would either measure the length, width and height or you could fill a beaker up with water lets say 50g and then put the object in the beaker and lets say it raised up to 80g all you have to do is subtract 80g-50g=30g. To find density with volume and mass you divide mass------volume and get density.
The question isn't valid because a gram is a unit of mass but a milliliter is a unit of volume. You would need to refer to a specific material's density to make a comparison. Density relates the volume of a material to its mass, but it can differ greatly based on the material in question. For example, 50g of lead occupies much less volume than 50g of water.
