What is the percent sulfur by weight in sulfur trioxide?
(32.07/80.07)*100 =40.0%
What is molecular weight of so2?
The relative atomic mass of sulfur is 32. And for oxygen, it is 16. Therefore the molecular weight of sulfur dioxide is 64 g/mol.
What is the formula mass for tin sulfate?
Tin sulfate is made out of the elements tin, sulfur and oxygen. The mass numbers of tin, oxygen and sulfur are 117, 16 and 32 respectively. Therefore the molecular weight of the empirical formula is 215 g/mol.
What weighs 1kg if it's dry and if it's wet then its weight is 2kg and if burned then its weight is 3kg?
Sulfur is closely match this puzzle. The density of 2 kg sulfur is double than 1 kg water. So if you weigh the sulfur in immersed state, the weight of sulfur will be 1 kg. Sulfur will displace about 1 kg water and will lose the same weight. After taking out of water, 2 kg sulfur will be 2 kg only. When you burn the sulfur, it will combine with 2 kg oxygen and you will get 4 kg of sulfur bi oxide. So it is fairly close to the answer. 3 kg literally means more than 2 kg. May be you know the better answer.
What is the weight of one mole of sulfur?
The molecular weight of 1 mole of sulfur is 32 amu or grams.
What is the percent sulfur by weight in sulfur trioxide?
(32.07/80.07)*100 =40.0%
How many ATOMS of sulfur are present in 9.96 grams of sulfur trioxide?
The formula for sulfur trioxide is SO3. The molecular weight is 80.06. The atomic weight of sulfur is 32.06. Therefore, the fraction by weight of sulfur in sulfur trioxide is 32.06/80.06 is 0.4004, to the justified number of significant digits, so that 9.96 grams of sulfur trioxide contains 3.988 grams of sulfur. The number of atoms present in 3.988 grams of sulfur therefore is Avogadro's Number X (3.988/80.06) or 3.000 X 1021 atoms, to the justified number of significant digits. (Note: A depressed final digit in a decimal means that the digit may not be significant.)
What is the empirical formula of a compound that is 4 percent sulfur and 6 percent oxygen by weight?
We can't tell. What's the other 90 percent? If you meant 40/60 instead... the mass of sulfur is twice that of oxygen, so a mass ratio of 40:60 is equivalent to an atom ratio of 1:3. The empirical formula would be SO3.
What is the percent by mass of sulfur in CuSO4?
Dehydrated copper sulfate contains approximately 12.8% sulfur by weight.
By weight 65 percent of you in what element?
Oxygen
What is molecular weight of so2?
The relative atomic mass of sulfur is 32. And for oxygen, it is 16. Therefore the molecular weight of sulfur dioxide is 64 g/mol.
What is the empirical formula of a compound that is 40percent sulfur and 60percent oxygen by weight?
SO3
By weight 65 percent of you is what element?
Oxygen
What percent of the weight of a typical plant is oxygen?
it is 77
How many percent of oxygen comprises on weight of earths continental crust?
Oxygen comprises about 47% by weight of Earth's crust
What is the empirical formula of a compound that is 40 percent sulfur and 60 percent oxygen by weight?
We assume 100 grams of compound and change % to grams. Get moles. 40 grams S (1 mole S/32.07 grams) = 1.247 60 grams O (1 mole O/16.0 grams) = 3.75 Now, the smallest mole value, sulfur, is 1. Divide the oxygen mole value by the sulfur mole value. 3.75 mole O/1.247 mole S = 3.00 SO3 ------- is the empirical formula
What is the mass of sulfur dioxide?
Sulfur is a non metal element. Atomic mass of it is 32.
