Moles of the soild = 1.78/ 208 = .00856 moles of H2O = 0.90/ 18 =.05
therefore number of moles of water for 1 mole of solid = .05/.00856 = approx 6
Dicyclohexyl chemical formula is C12H22 and the molecular weight is 166,3031 (not 200).
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
Cannot answer this question without knowing the EMPIRICAL formula.
The chemical formula of monosodium glutamate is C5H8NO4Na.
To calculate the number of grams in 4.1 x 10^22 molecules of N2I6, you first need to find the molar mass of N2I6. Then, use this molar mass to convert the number of molecules to grams using Avogadro's number and the formula: grams = (number of molecules) / (Avogadro's number) * molar mass.
Dicyclohexyl chemical formula is C12H22 and the molecular weight is 166,3031 (not 200).
To calculate the percentage of water in a hydrate, you first determine the molar mass of the water and the compound. Then, you divide the molar mass of the water by the molar mass of the hydrate and multiply by 100 to get the percentage.
To find the molecular formula, you need the empirical formula and molar mass. If the molar mass is 160 plus 5 grams per mole, the molecular formula cannot be determined without additional information about the empirical formula's molar mass relationship.
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. The molecular formula and the accurate molar mass would be N14O35.
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
The molar mass of nitrogen (N) is approximately 14 grams/mole, and the molar mass of oxygen (O) is approximately 16 grams/mole. Therefore, the molar mass of nitrogen dioxide (NO2) is 14 + (2*16) = 46 grams/mole to the nearest gram.
Cannot answer this question without knowing the EMPIRICAL formula.
The molar mass of NH2Cl is 51.5 g/mol, which means one mole of NH2Cl weighs 51.5 grams. The molecular formula of NH2Cl remains the same, NH2Cl, regardless of its molar mass.
To find the number of formula units in 22.4 grams of SnO2, you first need to determine the molar mass of SnO2, which is 150.71 g/mol. Next, calculate the number of moles in 22.4 grams using the formula: moles = mass / molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
