How do you solve for the empirical formula of a compound that contains 0.04 moles of sodium 0.04 moles of sulphur and 0.06 moles of oxygen?
To determine the empirical formula, first find the simplest whole number ratio of the moles of each element. In this case, you have 0.04 moles of sodium (Na), 0.04 moles of sulfur (S), and 0.06 moles of oxygen (O). Divide each amount by the smallest number of moles, which is 0.04: Na = 1, S = 1, and O = 1.5. To convert to whole numbers, multiply the ratios by 2, resulting in Na₂S₂O₃ as the empirical formula.
The number of moles of oxygen in the reaction vessel is?
To calculate the number of moles of oxygen in the reaction vessel, you need to know the amount of oxygen in grams and its molar mass. Then divide the mass of oxygen by its molar mass to obtain the number of moles. The formula to calculate the number of moles is: moles = mass / molar mass.
1.2 moles of oxygen atoms represent?
1.2 moles of oxygen atoms represent approximately 7.2 x 10^23 oxygen atoms. This is because 1 mole of any element contains Avogadro's number (6.022 x 10^23) of atoms. So, 1.2 moles would contain 1.2 times Avogadro's number of oxygen atoms.
Does two moles of O3 contain the same number of oxygen atoms as three moles of O2?
No, two moles of O3 contain 6 oxygen atoms, while three moles of O2 also contain 6 oxygen atoms. Each ozone molecule (O3) contains 3 oxygen atoms, while each oxygen molecule (O2) contains 2 oxygen atoms.
How many moles of O atoms are present in a 254g sample of carbon dioxide?
To find the number of moles of oxygen atoms in a 254 g sample of carbon dioxide (CO₂), first calculate the molar mass of CO₂, which is approximately 44 g/mol (12 g/mol for carbon and 32 g/mol for two oxygen atoms). The number of moles of CO₂ in the sample is 254 g ÷ 44 g/mol = about 5.77 moles. Since each molecule of CO₂ contains two oxygen atoms, the total number of moles of oxygen atoms is 5.77 moles × 2 = approximately 11.54 moles of O atoms.
Which element contains maximum number of moles- sulphur silver magnesium or carbon?
A mole of any chemical element contain the same number of atoms - the number of Avogadro.

How many oxygen atoms in 0.800 moles MgO?
In 0.800 moles of MgO, there are the same number of oxygen atoms as there are in 0.800 moles of O atoms. One mole of MgO contains one mole of oxygen atoms, which is equivalent to 6.022 x 10^23 oxygen atoms.
The mass of oxygen which contains the same number of atoms as those present in 64 grams of sulfur is?
The gram-atomic mass of sulphur is 32 and that of oxygen is 16, to two significant digits. Therefore, the mass of oxygen with the same number of atoms as 64 grams of sulphur can be found from the proportion m/64 = 16/32, or m = 32 grams.
The number of moles of oxygen in the reaction vessel is?
To calculate the number of moles of oxygen in the reaction vessel, you need to know the amount of oxygen in grams and its molar mass. Then divide the mass of oxygen by its molar mass to obtain the number of moles. The formula to calculate the number of moles is: moles = mass / molar mass.
How many moles of N2O3 contain 2.55 x 1024 oxygen atom?
To determine the number of moles of N2O3 containing 2.55 x 10^24 oxygen atoms, we first calculate the molar mass of N2O3, which is 76.01 g/mol. Next, we find the number of moles of oxygen atoms in 2.55 x 10^24 atoms by dividing the given number by Avogadro's number (6.022 x 10^23 atoms/mol). This gives us approximately 4.24 moles of oxygen atoms. Since each mole of N2O3 contains 3 moles of oxygen atoms, the number of moles of N2O3 containing 2.55 x 10^24 oxygen atoms is 4.24 moles / 3 = 1.41 moles.
How many moles of oxygen are in one mole of P4O10?
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
1.2 moles of oxygen atoms represent?
1.2 moles of oxygen atoms represent approximately 7.2 x 10^23 oxygen atoms. This is because 1 mole of any element contains Avogadro's number (6.022 x 10^23) of atoms. So, 1.2 moles would contain 1.2 times Avogadro's number of oxygen atoms.
Does two moles of O3 contain the same number of oxygen atoms as three moles of O2?
No, two moles of O3 contain 6 oxygen atoms, while three moles of O2 also contain 6 oxygen atoms. Each ozone molecule (O3) contains 3 oxygen atoms, while each oxygen molecule (O2) contains 2 oxygen atoms.
A balloon contains 7.36 g of oxygen gas (O2). How many oxygen molecules are in the balloon?
To find the number of oxygen molecules in the balloon, you can first calculate the number of moles of O2 using its molar mass (32 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. In this case, the balloon contains approximately 1.15 x 10^23 oxygen molecules.
How mony moles of oxygen atoms do 1.5 moles of Co2 contain?
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
