How do you find the density of a block?
it is easy. You use Mass divided by Volume. You can Remember it by a heart. The top is a M and the bottom is a V. Mass divided by volume. <3
What is the atomic mass of lead?
Lead's atomic mass is 207.2 Its atomic number is 82
How could you increase the mass of a wooden block?
-- Paint it -- Soak it in water -- ail or glue more wood to it -- Bury a piece of lead in it -- Move it past you at ginormous relativistic speed
How many grams of lead are in 4.62 moles of lead?
Mole times Lead's Molecular mass(Mr) gives you its mass And I think the Mr of Lead is 207
If you have a sample of lead that is 140.0 cm3 how do you find its mass in grams?
By looking up it's density in a book. The density of lead is 11.34 g/cm3 at room temperature. So the mass of a 140.0 cm3 sample of lead is 11.34 g/cm3 * 140.0 cm3 = 1588 g
The mass of a wooden block is 5 kg and its dimensions of 40 cm 20cm 10 centimetre find the pressure exerted by the wooden block on the tabletop a 20cm 10cm g 9.8 m per second square?
2450N per metre square
What is the density of a block of wood that has a volume of 20cm and mass of 5 grams?
density is the product of mass and volume so its density will b 100 g/cm3..
What do you use to find the mass of a block of wood?
To find the mass of a block of wood you should use a triple beam balance.
How do you find the mass of a block of wood?
Measure it.
What is the volume of a block of lead with the mass of 282.5 g?
Density = Mass/Volume so Volume = Mass/Density The density of lead is 11.3 grams per cm3 so volume = 282.5/11.3 = 25 cm3
Does every substance have its own mass-to-volume ratio?
Yes, the mass-to-volume ratio - commonly called the density - is a typical amount for any substance. For example, you can have a large block of lead, which is heavy, and a small block of lead, which is much lighter. But the density (mass-to-volume ratio) will be the same for both - about 11,000 kg/m3.
How do you find the density of a block of wood?
you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume
How do you get a density of a block?
You will need the mass and volume of the block. To find mass, use an electronic balance. To find volume, use length x breadth x height. For irregular solid, use the water displacement method. The density is mass divided by volume.
Which two tools would help you determine the density of a block?
Something to determine volume (like a bucket of water or a ruler), and a balance to determine mass. Divide the mass of the block by its volume to find the density of the block.
What is the mass of a rectangular container measuring 10cm x 20cm x 25cm?
1000 cm
When using an atwood's machine how do you find the mass of the block that's pulling it down?
345
What is the density of an object that has 100 gram mass and 20cm to the third power volume?
5 gm/cc
