How many atoms of aluminum are there in a sample of aluminum sulfide with a mass of 100 g?
Aluminum sulfide has a molar mass of 150.16 grams per mole. This means there are 0.666 moles present, or 4.01 E23 molecules. Each molecule of Al2S3 has 2 aluminum atoms, so there are 8.02 E23 atoms of aluminum present.
What has more mass 100 hydrogen atoms 4 sulfur atoms or 1 lanthanum atom?
100 Hydrogen atoms have an atomic mass of 100.794, 4 Sulfur atoms have an atomic mass of 128.26, and 1 Lanthanum atom has an atomic mass of 138.90547.
What are the 100 types of atoms?
There are 118 known elements, not 100 types of atoms. Elements are made up of atoms with specific numbers of protons in the nucleus. The first 92 elements occur naturally, with the rest being synthetic and created in laboratories.
What is the percent composition of O in Aluminum Sulfate?
There is 9.2758% Al3+ in a formula unit of aluminum oxide.AnswerThe formula for aluminum oxide is Al2O3: Molar mass =581.77g/mol Al2O3. In one mole Al2O3, there are two moles of Al3+ ions, therefore 2 moles Al3+ x 26.982g/mol Al3+ = 53.964g Al3+ in one mole of Al2O3.GIVEN: mass of Al3+ = 53.964 gAl3+;Molar mass of Al2O3 = 581.77 gAl2O3WANTED: % Al3+EQUATION:% Al3+...=...g Al3+x 100...g Al2O3% Al3+...=...53.964gAl3+x100......=...9.2758%Al3+581.77g Al2O3
How many atoms does 100 grams of gold have?
To find the number of atoms in 100 grams of gold, you would first calculate the number of moles using the molar mass of gold (197 grams/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, approximately 3.01 x 10^23 atoms of gold are present in 100 grams.

How many atoms of aluminum would be in a 100 grams of aluminum?
The number of aluminium atoms ia 0,44638973.10e23.
What is heaver 25 kilograms or 100 pounds?
100 pounds is heavier than 25 kilograms.Divide both sides by 25.4 pounds are heavier than 1 kilogram.
Which is heavier 100 ounces or 3 kilograms?
100 ounces = 2.83495 kg. So, 3 kg is heavier.
Which is heavier 100 milligram or 100 grams?
100 grams is heavier than 100 milligrams. 1 gram is equal to 1000 milligrams, so 100 grams would be equivalent to 100,000 milligrams.
Which is heavier a 10 pound rock or a 100 ounce rock?
A 10 pound rock is heavier. There are 16 ounces in a pound and 16x10 is 160. 160 is larger than 100.
What is heavier 100 kilograms or 100 pounds?

Which is heavier - a pound or 100 grams?
One pound is is about 4.5 times heavier than 100 grams.
How many times heavier is 7.5 kg than 75 g?
100 times
Is there any way aluminum is bad?
Aluminum takes more than 100 years to decay. If this were to be thrown in the garbage, it would take up to 100 years completely decay.
Is 100 pounds of steel heavier than 100 pounds of feathers?
No, 100 pounds of steel is not heavier than 100 pounds of feathers; they both weigh the same—100 pounds. The difference lies in their volume and density: steel is much denser than feathers, so 100 pounds of steel would occupy a much smaller space compared to 100 pounds of feathers, which would take up a significantly larger volume.
What is heavier than a gram?
In the metric system 100 g = 1 kg. 1000 kg = 1 tonne. So both kg and tonne are heavier than a g ) gram).
