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

What is the volume of a sample with 96.2 grams?
It depends entirely on what substance you're working with. For example, the volume of 96.2 grams of hydrogen is a lot more than the volume of 96.2 grams of lead.
A sample has a mass of 612 grams and a volume of 78 cm3 What is the identity of the sample?
The first reference I consulted on line lists the density of gold as 19.32 gm/cm3,whereas the density of your sample is 19.286 gm/cm3.
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 is 10.7 g/mL. The sample is not pure lead because the density of pure lead is 11.3 g/mL.
Grams in 33.3 moles of lead?
Pb molecular weight is 207.2 g/mol. 33.3 moles of Pb weighs 6899.76 grams.
How many grams of lead is needed to equal the number of atoms contained in 10 grams of tin?
Let us do this in two parts for clarity. Find atoms in tin first. 10 grams tin (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn) = 5.07 X 1022 atoms of tin ----------------------------------- 5.07 X 1022 atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 17 grams of lead ------------------------------ I can see two other ways to do the conversion string, one longer and one much shorter. See if you can find them.
What is the volume of a 17.6 grams sample of lead?
Divide the number of grams by the density (the density of lead is about 11 grams/cubic centimeter - look it up if you need more precision). If the density is in grams/cubic centimeter, the answer is the volume in cubic centimeters.

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 weighs more ten grams of lead or ten grams of bubble gum?
Ten 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
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 is 10.7 g/mL. The sample is not pure lead because the density of pure lead is 11.3 g/mL.
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.
How many atoms in 10 grams of lead?
10 grams lead (1 mole Pb/207.2 grams)(6.022 X 1023/1 mole Pb) = 2.9 X 1022 atoms of lead -----------------------------------
What is Sample of physical change?
For example melting of lead.
