To find the number of molecules in 10 grams of oxygen gas (O₂), we first calculate the number of moles. The molar mass of O₂ is approximately 32 g/mol. Therefore, 10 g of O₂ is about 0.3125 moles (10 g / 32 g/mol). Using Avogadro's constant (approximately 6.02 x 10²³ molecules/mol), the number of molecules is about 1.88 x 10²³ molecules (0.3125 moles x 6.02 x 10²³ molecules/mol).

A balloon contains 7.36 g of oxygen gas. how many oxygen molecules are in the balloon?
To find the number of oxygen molecules in 7.36 g of oxygen gas (O₂), we first calculate the number of moles. The molar mass of O₂ is approximately 32 g/mol. Thus, the number of moles in 7.36 g is 7.36 g / 32 g/mol = 0.230 moles. Using Avogadro's number (approximately 6.022 x 10²³ molecules/mol), the total number of molecules is 0.230 moles × 6.022 x 10²³ molecules/mol ≈ 1.38 x 10²³ molecules.

How many oxygen molecules are there in in 4 g of oxygen?
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules

A vat of hydrogen peroxide H2O2 contains 455 grams of oxygen atoms how many molecules of H2O2 are in the vat?
To find the number of molecules of H2O2 in the vat, we first need to calculate the number of moles of oxygen atoms. Using the molar mass of oxygen (16 g/mol), we find that 455 grams of oxygen is equivalent to 28.44 moles. Since each molecule of H2O2 contains 2 oxygen atoms, the number of H2O2 molecules in the vat would be 2 times Avogadro's number (6.022 x 10^23) times the number of moles of oxygen atoms, or approximately 3.43 x 10^24 molecules.
