What is the molar mass of sulfur dioxide (SO2)?
The sulfur dioxide formula, SO 2, shows that its molecules contain one S atom and two O atoms; calculate its molar mass. One mole SO 2 contains 6.02 x 10 23 SO 2 molecules, which consist of 6.02 x 1023 S atoms and 2(6.02 x 10 23) O atoms. Same for ionic compounds, such as potassium sulfide (K 2 S): 9
What is the mass of one gram of oxygen in moles?
Naturally occurring sulphur is usually S8. Therefore the number of moles of sulphur = mass / molar mass = 8 / (32*8) = 1 / 32 moles of sulphur. The same number of molecules of oxygen is then also 1 /32 moles. Therefore the mass of oxygen (which is diatomic in nature) = number of moles x molar mass = 1 /32 x (2 x 16) = 1 gram of oxygen.
What is the mass percent of oxygen in CO2 in grams?
mass \% O = (mass of 1 mol of oxygen/mass of 1 mol of CO 2) x 100; mass \% O = (32.00 g / 44.01 g) x 100; mass \% O = 72.71 \%
How many molecules are there in 32 grams of oxygen?
Chemical formula of Oxygen is O2. 1 mole of a substance contains 6.022×10^23, Avogadro’s Constat. 32g of O2 = 6.022×10^23 molecules. What mass of oxygen contains the same number of molecules as 8 grams of sulphur? The answer is 1 gram of oxygen. Here’s how I worked it out: Naturally occurring sulphur is usually S8.

What does sulfur look like in molten state?
Sulfur, molten appears as a pale yellow crystalline solid with a faint odor of rotten eggs. Insoluble in water. A fire and explosion risk above 450° F. Transported as a yellow to red liquid. Handled at elevated temperature (typically 290°F) to prevent solidification and makes transfers easier.
What is the percentage of sulfur in pure sulfur?
Sulfur, puriss., 99.5-100.5\%, meets analytical specification of Ph. Eur., BP, USP, precipitated Sulfur, molten appears as a pale yellow crystalline solid with a faint odor of rotten eggs. Insoluble in water.
