How many molecules are in 26.3 g of calcium hydroxide?
26.3 g of calcium hydroxide contain 2,054 molecules.
The empirical formula of a compound is CH2O The molar mass of the compound is 180 g What is the molecular formula for this compound?
The empirical formula CH2O has a molar mass of 30 g/mol (12 g/mol for C + 2 g/mol for H + 16 g/mol for O). To find the molecular formula, which is a multiple of the empirical formula, you divide the molar mass given (180 g/mol) by the empirical formula mass (30 g/mol), giving you 6. Therefore, the molecular formula for the compound is (CH2O)6, which simplifies to C6H12O6, the molecular formula for glucose.
How many molecules are in 32 g of SO2?
32 g SO2 x 1 mole SO2/96 g x 6.02x10^23 molecules/mole = 2.0x10^23 molecules
How many molecules (not moles) of NH3 are produced from 1.57104 g of H2?

How many O2 molecules are needed to react with 7.45 g of S?
1,4.10e23 molecules
How many molecules of CH2O are in 50.0 g of CH2O?
To find the number of molecules in 50.0 g of CH2O, you need to first calculate the number of moles of CH2O using its molar mass (30.03 g/mol). Next, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles into molecules. Therefore, 50.0 g of CH2O contains approximately 1.66 x 10^24 molecules.
How many molecules of nitric acid are in 300 g of nitric acid?
The number of nitric acid molecules is 28,6723.10e23.
What is the mass of 4.55 moles of CH2O?
To calculate the mass of 4.55 moles of CH2O, you need to multiply the molar mass of CH2O by the number of moles. The molar mass of CH2O is approximately 30.03 g/mol. Therefore, the mass of 4.55 moles of CH2O is 136.665 g.
What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.1g?
The empirical formula CH2O has a molar mass of 30.03 g/mol (12 g/mol for C + 2 g/mol for H + 16 g/mol for O). To find the molecular formula, divide the molar mass given (120.1 g/mol) by the molar mass of the empirical formula to get 4. This means the molecular formula is (CH2O)4, which simplifies to C4H8O4.
How many atoms of hydrogen 31 grams in CH2O?
To find the number of moles in 31 grams of CH2O, we divide the mass by the molar mass of CH2O (30.03 g/mol). This gives us approximately 1.03 moles of CH2O. Since there are two hydrogen atoms in each molecule of CH2O, we multiply the number of moles by Avogadro's number (6.02 x 10^23) and by 2 to find about 1.24 x 10^24 hydrogen atoms.
