32 as oxygen is diatomic
To calculate the mass of 1.0 x 10^12 molecules of O2, you need to first determine the molar mass of O2, which is approximately 32 g/mol. Then, divide the number of molecules by Avogadro's number to convert to moles, and finally multiply by the molar mass to find the mass. The mass of 1.0 x 10^12 molecules of O2 would be approximately 0.53 grams.
Two moles of O2 molecules would have a mass of 64 grams (2 moles x 32 grams/mole = 64 grams).
The molar mass of oxygen is approximately 16 grams per mole. This means that one mole of oxygen molecules (O2) would have a mass of 32 grams, since each molecule of O2 consists of 2 oxygen atoms.
The balanced chemical equation for the reaction between Mg and O2 is 2Mg + O2 -> 2MgO. This equation shows that 1 mole of Mg reacts with 1 mole of O2. The molar mass of O2 is 32 g/mol. Therefore, 21.0 g of Mg will react with 16.0 g of O2, which is 0.5 moles of O2.
To find the number of moles in 150.0 g of O2, first calculate the molar mass of O2, which is 32.0 g/mol (16 g/mol for each oxygen atom). Then, divide the given mass by the molar mass to get the number of moles: 150.0 g / 32.0 g/mol = 4.69 moles of O2.
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
No; 1 mole of molcular oxygen (O2) is 31,998 g and 1 mole of sulfur (S) is 32,06 g.

The mass of 3.2 moles O2? The atoms in 3.2 moles O2 Could be other things, I guess, but I will do these two. 3.2 moles O2 (32 grams/1 mole O2) = 102.4 grams of gaseous oxygen -------------------------------------------- 3.2 mole O2 (6.022 X 1023/1 mole O2) = 1.9 X 1024 atoms of gaseous oxygen --------------------------------------------------
To determine the mass of NO2 formed when NO reacts with O2, we need to write and balance the chemical equation for the reaction. The balanced equation is 2NO + O2 -> 2NO2. From the equation, we see that 2 moles of NO will react with 1 mole of O2 to produce 2 moles of NO2. Next, we need to calculate the number of moles of O2 present in 384g using its molar mass. Finally, we can use the mole ratio from the balanced equation to find the mass of NO2 formed.
No, the (molar) mass (ie. the mass of one mole) is different by factor 2.004:Oxygen atom (O)15.999 g/mole O2,Oxygen molecule (elemental gas, O2) 31.998 g/mole O2Sulfur atom (S) 32.06 g/mole S,Sulfur molecule (bright yellow solid, S8) 256.48 g/mole S8,Sulfur molecule (S2) 64.12 g/mole S2 (there are more than 20 other allotropes)

Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
The molar mass of oxygen is approximately 16 grams per mole. This means that one mole of oxygen molecules (O2) would have a mass of 32 grams, since each molecule of O2 consists of 2 oxygen atoms.
1 mole of HgO produces 1 mole of O2 according to the balanced chemical equation for the reaction. Therefore, 0.440 moles of HgO will produce 0.440 moles of O2.
To calculate the mass of 1.5 moles of oxygen molecules (O2), you multiply the number of moles (1.5) by the molar mass of oxygen (O2). The molar mass of O2 is approximately 32 g/mol. So, the mass of 1.5 moles of oxygen molecules would be 1.5 moles * 32 g/mol = 48 grams.
