Would a heavy piece of wood that measures 2cmx10cmx5cm and its mass is 89g will it float?
volume=100cm3 mass=89gm density=m/v=89/100=0.89 density of water=1 so it will float
What is the density of a block of aluminum that has a mass of twenty seven grams and a volume of ten centimeters to the third power?
Density = (mass) / (volume) = 27/10 = 2.7 gm/cm3 .
If an object has mass of 250g and volume of 125 cm time 3 what is the desity?
Density is equal to mass divided by volume (d= m/v). So m= 250 g and v = 125 cm cubed (cm3), there fore density is 2 g/cm3.
How do you calculate mass of a liquid when volume is unknown?
You can use the density of the object. Density is the mass per unit volume of a substance. Density = mass / volume. Rearrange it to solve for mass. Mass = density x volume. You can find the density of the substance from a table of densities. Or depending on what you know about the substance:- moles = volume (dm3) x concentration (moldm-3) moles = mass/Mr Mr = molecular weight 100cm3 = 0.1dm3 If you know the volume, concentration and the Mr then mass can be solved by calculating the moles of the substance and multiplying by Mr.
Does a crumpled piece of aluminum foil into a ball would the mass weight volume and density increase or decrease from what it was?
All that has changed is the shape.
If a rock sample has a mass of 250g and a volume of 45 cm3 show the calculation for the density of the rock sample?
density = mass/volume = 250g/45cm3 = 5.6g/cm3 (rounded to 2 sig figs)
What is the mass of a chunk of aluminum?
The mass and volume of aluminum are related by density: mass = volume x density and density depends upon temperature and pressure. Aluminum has a density of 2.70 grams per cubic centimeter in its solid state. In its liquid state, Aluminum has a density of 2.375 grams per cubic centimeter.
Would a heavy piece of wood that measures 2cmx10cmx5cm and its mass is 89g will it float?
volume=100cm3 mass=89gm density=m/v=89/100=0.89 density of water=1 so it will float
How does mass and volume determine the density of aluminum?
If you divide the mass by the volume, for any object, you get its density.
How do you find the mass of 50 grams of aluminum?
the mass is the 50 grams you probably need the volume volume = mass / density get the density from tables
What materials you need to find the density of aluminum?
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
You have a rock with a volume of 15 cm3 and a mass of 45 g.?
45/15= 3 Where density is equal to mass over volume
What is the mass and the volume of an aluminum foil which has a density of 2.7gcm3?
We can't tell that from the density. All we know is that however much aluminum foil you have ... whether it's a tiny scrap or a truckload ... each cm3 of it has 2.7g of mass.
A block of aluminum aluminum occupies a volume of 15.0 ml and weighs 40.5 g what is its density?
By definition: Density is equal to the mass divided by the volume. You have a volume of 20 ml and a mass of 54 g.
What is the volume of aluminum if the mass is 5.40?
Since the density of aluminum is 2.7 g cm-3, a sample with a mass of 5.4 would have a volume of 2 cm3.
Calculate the mass of aluminum that occupies the same volume as 66.7 g of cobalt The density of cobalt is 8.90 gcm3 and the density of aluminum is 2.71 gcm3?
20.3g Al
How can you find the density of a can of soda pop?
To find the average density of the can and its contentsWeigh the can of soda pop (mass) and then divide by the number of cubic centimeters in the can (volume). Density = mass/volume.To find the density of the aluminum canEmpty the can completely, weigh it, then place it in a filled liquid container to determine the volume of the aluminum. Divide as above to find the density of the aluminum (should be approximately 2.7 grams per cubic centimeter).
