To find the mass of a lead block, you'll need to know the density of lead. With the dimensions of the block (20 cm x 20 cm x 10 cm) and the density of lead (11.34 g/cm^3), you can calculate the volume of the block (20 cm x 20 cm x 10 cm = 4000 cm^3) and then multiply it by the density to find the mass. In this case, the mass of the lead block would be 4000 cm^3 x 11.34 g/cm^3 = 45360 grams or 45.36 kg.

How do you find the density of a block?
To find the density of a block, calculate the block's mass and volume. Then, divide the mass by the volume to get the density. The formula is density = mass/volume.
Instrument you would use in the laboratory to find the mass of the block?
You would use a balance or a scale to find the mass of the block in the laboratory. These instruments provide accurate measurements of mass by comparing the weight of the object with a set of calibrated weights.
If you have a sample of lead that is 140.0 cm3 how do you find its mass in grams?
To find the mass of lead in grams, you would need to know the density of lead. The formula to calculate mass is mass = density x volume. The density of lead is approximately 11.3 g/cm3. Once you have the density value, you can input 140.0 cm3 into the formula to find the mass in grams.
How many grams of lead are in 4.62 moles of lead?
To find the grams of lead in 4.62 moles, you can use the molar mass of lead, which is approximately 207.2 g/mol. Multiply the number of moles by the molar mass to get the grams: 4.62 moles * 207.2 g/mol β 956.6 grams of lead.
What is the density of a block of wood that has a volume of ml and a mass of g?
To calculate the density of the block of wood, you would divide its mass (in grams) by its volume (in milliliters). The formula for density is: Density = Mass / Volume. Plug in the values for mass and volume to find the density of the block in g/mL.
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?
The density of the wood block is calculated by dividing the mass (5 grams) by the volume (20 cm^3). Therefore, the density of the wood block is 0.25 g/cm^3.
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.
How do you find the density of a block?
To find the density of a block, calculate the block's mass and volume. Then, divide the mass by the volume to get the density. The formula is density = mass/volume.
A 38 kg block of lead is heated from -26C to 180C how much heat energy does the block of lead absorb to increase his temperature this much?
To find the heat energy absorbed by the lead block, you need to use the specific heat capacity of lead, which is 128 J/kgΒ°C. The formula to calculate heat energy is: Q = m * c * ΞT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΞT is the change in temperature. Plugging in the values, you can find the heat energy absorbed by the lead block.
Is lead heavier than iridium?
Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier
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
Instrument you would use in the laboratory to find the mass of the block?
You would use a balance or a scale to find the mass of the block in the laboratory. These instruments provide accurate measurements of mass by comparing the weight of the object with a set of calibrated weights.
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
Which two tools would help you determine the density of a block?
To determine the density of a block, you can use a balance to measure its mass and a ruler to measure its dimensions. The density of the block can then be calculated by dividing the mass by the volume.
