How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many grams are in 4 molecules of water?
The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, for 4 molecules of water, the total mass would be 4 x 18 = 72 grams.
How many molecules are there in 29.777 grams of hydrogen peroxide H2O2?
To find the number of molecules in 29.777 grams of hydrogen peroxide (H2O2), you first need to calculate the number of moles in 29.777 grams using the molar mass of H2O2. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
How many molecules are there in 200 grams of h2o?

How many molecules are contained in 55 grams of sulfuric acid?
To calculate the number of molecules in 55 grams of sulfuric acid (H2SO4), you first need to determine the molar mass of sulfuric acid, which is 98.08 g/mol. Next, find the number of moles in 55 grams by dividing the mass by the molar mass. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many grams are in 8.2 x 1022 molecules f N2l6?
To find the mass in grams of 8.2 x 10^22 molecules of N2l6, we first need to determine the molar mass of N2l6. The molar mass is calculated by adding the atomic masses of nitrogen (N) and iodine (l) in the formula. N has an atomic mass of approximately 14 g/mol and I has about 127 g/mol; thus, N2l6 has a molar mass of (2 * 14) + (6 * 127) = 868 g/mol. Next, we convert the number of molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol): 8.2 x 10^22 molecules * (1 mol / 6.022 x 10^23 molecules) ≈ 0.136 moles. Finally, we multiply the number of moles by the molar mass: 0.136 moles * 868 g/mol ≈ 118.5 grams. Therefore, there are approximately 118.5 grams of N2l6 in 8.2 x 10^22 molecules.
