What do you mean by "heaviest"? If you have a lot of feathers, it weighs more than a little bit of lead! There are two ways to interpret this question. One is, "Which is the element with the highest atomic weight?", and "What is the element with the highest density?"
The element with the highest atomic weight is the heaviest for the same number of atoms, and the most dense element is the heaviest element for the same volume of material.
The answer is different depending on the interpretation, so I'll give both answers.
Lead has a larger atomic weight than mercury. The atomic weight of lead is 207.2 grams per mole, while the atomic weight of Mercury is 200.59.
However, mercury is more dense than lead. The density of mercury is 13.53 grams per cm3, and the density of lead is only 11.4 grams per cm3.
So if you had the same number of atoms of each, the lead would be heavier. If you had the same volume of each, the mercury would be heavier!

∙ 13y agoNo it is not. it is Osmium which has the highest density.
Actually, in 2009, German scientists created Ultra-Dense Deuterium in minute quantities, a 10-cm cube of which would weigh about 130 tonnes.

∙ 12y agoThe density of mercury is 13,534 grams per cm3, and the density of lead is only 11,34 grams per cm3.
The weight of 20 cm3 of lead is 226,8 grams.
The weight of 20 cm3 of mercury is 270,68 grams.

∙ 14y agoVery. It is about 13.5 times as dense as water. One litre of water weighs one kilogram, so a litre of mercury weighs 13.5 kg. For comparison, a litre of steel weighs about 8 kg.

What is the density of a box that weighs 190 g and the volume is 20 cm3?
Because d=M/V: d= 190/20= 9,5 g/cm3.
What is the density of mercury if 20.0cm3 has a mass of 272 grams?
Density is measured in kilograms per metre cubed, kgm-3, because a gram and a litre are both one thousnadths of their base unit, density can also be written as grams per litre. A density of 5 kgm-3 is the same as 5gl-1. A volume of 2.0 ml with a mass of 27.1 g would have a density of 27.1 grams per 0.002 litres, or 27.1/0.002 gl-1. which calculates as 13 550 gl-1, which is the same as 13 550 kgm-3.
What is the density of an object with a mass of 100.8g and a volume 144cm3?
The object has a density of 0.7 g/cm3
How high in meters must a column of water be to exert a pressure equal to that of a 760mm column of mercury?
The density of mercury is 13.534 grams per cm3 so mercury is approx 13.5 times denser than water (the density of water is not exactly 1). Therefore you would need a column of 20/13.5 = 1.48 cm of mercury.
What is heavier 40 kilograms or 20 pounds?
The conversion is (approximately) 2.2 pounds per kilogram, so 40kg is a little over four times heavier than 20 lb.
What is the average density of mercury?
1. The chemical element has a density of 15,534 g/cm3 at 20 0C. 2. The planet Mercury has a density of 5,427 g/cm3.
Mass of Mercury?
The density of the metal mercury (liquid) is 13,534 kg/m3 or (liquid) 13.534 g/cm3. The correct SI measure of the density is kg/m3.
Weight of 1966 mercury 20 hp?
it is 88 pounds. That's only 40 kg, it certainly felt heavier than that when I was a kid :)
Which is less dense 20g and 10 cm3 or 20g and 2 cm3?
Just divide to get the density, and compare. 20 / 10 = 2 g/cm3, 20/2 = 10 g/cm3, so the first is less dense.
What is the mass of 7.76 ml of mercury of density 13.6 g per ml?
7.76 x 13.6 = 105.536 g At a temperature of 20 0C the density of extrapure mercury is 13,534 g/cm3 and the mass will be 105,023 84 g.
Is the volume of gold 20g greater than the volume of lead 10g?
We need to calculate the volume of a metal from the density to be sure. Density of pure gold = 19.3  g·cm-3Density of pure lead = 11.34  g·cm-3The volume of 20 g of gold = mass/density = 20 [g] / 19.3  g·cm-3 = 1.036 cm3 The volume of 10 g of lead = mass/density = 10 [g] / 11.34  g·cm-3 = 0.882 cm3 Hence, the volume of 20 g of gold is slightly greater than that of 10 g of lead. =========================
What is the mass of 1.0L of air if the density of air equals 1.2 g cm cubed?
1 Liter = 1,000 mL = 1,000 cm3 (1.2 gm/cm3) x (1,000 cm3/L) = (1.2 x 1,000) (gm - cm3 / cm3 - L) = 1,200 gm/L This is the solution per the numbers postulated in the question, but the whole situation is suspicious. That's an awfully large density given for air ... in fact, it's actually about 20% heavier than water.
What is the density of a unknown solid if it has a volume of 20 cm3 and a mass of 190 g?
density = mass / volume =190 / 20 =9.5g/cm3
Is the mass of sugar 20 cm3?
No. It cannot be. Mass cannot be measured in cm3, which is a measure of volume.
Do water acid mercury and alcohol have the same density?
No. They have very different densities. There are several types of alcohol, but for these purposes, we will use ethanol, the alcohol found in drinks. Density of water ≈ 1g/cm3 Density of ethanol = 0.789g/cm3 Density of mercury = 13.5 g/cm3 So water is about 20% denser than alcohol, and mercury is more than 13 times denser than water. Note that the density given from ethanol is for pure ethanol. Most alcoholic beverages are mixtures, with densities between those of water and pure ethanol.
What is the density of an object with a volume of 12 cm3 and a mass of 20g?
density = mass ÷ volume= 20 g ÷ 12 cm3≈ 1.67 g/cm3
What is the density of a box that weighs 190 g and the volume is 20 cm3?
Because d=M/V: d= 190/20= 9,5 g/cm3.
