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

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 ≈ 956.6 grams of lead.
What is the volume of a sample with 96.2 grams?
To determine the volume of a sample with a given mass (96.2 grams), you need to know the density of the substance. The volume can be calculated using the formula: Volume = Mass / Density. Without knowing the density of the substance, it is not possible to calculate the volume.
Grams in 33.3 moles of lead?
The molar mass of lead (Pb) is approximately 207.2 g/mol. To find the mass of 33.3 moles of lead, you would multiply the number of moles by the molar mass: 33.3 moles * 207.2 g/mol = approximately 6890.76 grams of lead.
A sample has a mass of 612 grams and a volume of 78 cm3 What is the identity of the sample?
To determine the identity of the sample, you would need the density of the material it is made of. Density is calculated by dividing mass by volume (density = mass/volume). Without this information, it is not possible to accurately determine the identity of the sample.
A sample thought to be pure lead occupies a volume of 15.0 mi.and has a mass of 160.0g.determine the density and is the sample pure lead?
The density of the sample is calculated by dividing the mass (160.0g) by the volume (15.0 mi^3), which results in 10.67 g/cm^3. The density of pure lead is known to be 11.34 g/cm^3, suggesting that the sample is not pure lead but likely a different material with a lower density.
What is the volume of a 17.6 grams sample of lead?
To find the volume of a sample of lead, you need to know its density. The density of lead is 11.34 grams per cubic centimeter. You can calculate the volume by dividing the mass of the lead sample by its density. In this case, the volume of a 17.6 gram sample of lead would be approximately 1.55 cubic centimeters.
A 2.0 mole sample of lead would have a mass of?
The molar mass of lead (Pb) is approximately 207.2 g/mol. Therefore, a 2.0 mole sample of lead would have a mass of 414.4 grams (2.0 moles x 207.2 g/mol).
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 ≈ 956.6 grams of lead.
Why is 2kg sample of lead denser than 10kg sample of iron?
Density is a weight per unit volume calculation. There could be different alloys or casting methods with subtle differences in density, or temperature variations in expansion and density. However: Every cubic centimeter of lead weighs 11.34 grams. Every cubic centimeter of iron weighs 7.86 grams. Thus, the density of lead (11.34 g/cc) is greater than iron (7.86 g/cc). This is independent of the actual weight and volume of the sample.
Which has the greater density 5 kg of lead or 10 kg of aluminum?
No matter how much of a sample you have, its density is the same. So 1g of lead has the same density as 1,000kg of lead. To find out which is more dense, just look it up somewhere. Or look at the periodic table. Lead's atomic mass is much greater than aluminum's, suggesting that it is more dense.
What is the volume of a sample with 96.2 grams?
To determine the volume of a sample with a given mass (96.2 grams), you need to know the density of the substance. The volume can be calculated using the formula: Volume = Mass / Density. Without knowing the density of the substance, it is not possible to calculate the volume.
Grams in 33.3 moles of lead?
The molar mass of lead (Pb) is approximately 207.2 g/mol. To find the mass of 33.3 moles of lead, you would multiply the number of moles by the molar mass: 33.3 moles * 207.2 g/mol = approximately 6890.76 grams of lead.
Calculate the number of grams of lead Pb in 12.4 moles of lead?
1 mol Pb = 207.2 grams 12.4 mol Pb = ? grams (cross multiplication) mass of (12.4 mol Pb) = (207.2 gr *12.4 mol) / (1mol) = 2569.28 g
What weighs more ten grams of lead or ten grams of bubble gum?
Both ten grams of lead and ten grams of bubble gum would weigh the same amount because they both weigh ten grams. The weight is determined by the measure of grams, not the material being weighed.
What does PB sample mean in medical terminology?
Pb is the chemical abbreviation for lead, so perhaps it refers to a sample taken for lead level testing.
A sample has a mass of 612 grams and a volume of 78 cm3 What is the identity of the sample?
To determine the identity of the sample, you would need the density of the material it is made of. Density is calculated by dividing mass by volume (density = mass/volume). Without this information, it is not possible to accurately determine the identity of the sample.
Which quantity is quivalent to 39 grams of lif?
39 grams of lead is equivalent to approximately 0.36 moles of lead.
