What is the mass of 3.01 x 1023 formula units of Fe2O3?
To find the mass of 3.01 x 10^23 formula units of Fe2O3, you first need to calculate the molar mass of Fe2O3. The molar mass of Fe2O3 is 159.69 g/mol. Then, you multiply the molar mass by the number of formula units given (3.01 x 10^23) to find the total mass. The mass of 3.01 x 10^23 formula units of Fe2O3 would be 4.81 x 10^25 grams.
How many formula units are in 5.6 g of H2S?
To calculate the number of formula units in 5.6 g of H2S, you first need to determine the molar mass of H2S, which is 34.08 g/mol. Then, you can use the formula: Number of formula units = (mass given / molar mass) * Avogadro's number. Plugging in the values, you get: (5.6 g / 34.08 g/mol) * 6.022 x 10^23 = 9.89 x 10^22 formula units in 5.6 g of H2S.

What is the formula weight of rust?
Rust is a compound primarily composed of iron(III) oxide, with a chemical formula of Fe2O3. To calculate the formula weight, you would add the atomic weights of two iron atoms (Fe) and three oxygen atoms (O) together. Using the atomic weights from the periodic table, the formula weight of rust (Fe2O3) would be approximately 159.69 g/mol.

What is the mass of 5.55 1022 formula units of calcium chloride CaCl2?
The molar mass of CaCl2 is 110.98 g/mol. To find the mass of 5.55 x 10^22 formula units, you would multiply the molar mass by the number of formula units. This gives a mass of approximately 6.16 x 10^24 grams.
A salt crystal has a mass of 0.16 How many formula units does it contain?
To determine the number of formula units in a salt crystal, you need to know the molar mass of the salt. Once you know the molar mass, you can use it to calculate the number of moles present in the crystal, and then convert that to the number of formula units using Avogadro's number, which is 6.022 x 10^23 formula units/mol.
What is the mass of 0.7891 mol of ferric oxide Fe2O3?
To find the mass of 0.7891 mol of ferric oxide (Fe2O3), you need to calculate the molar mass of Fe2O3. The molar mass of Fe2O3 is 159.69 g/mol. Multiply the molar mass by the number of moles to find the mass: 0.7891 mol * 159.69 g/mol ≈ 125.94 g. Therefore, the mass of 0.7891 mol of Fe2O3 is approximately 125.94 grams.
What is the formula to calculate density and units?
Density = Mass/Volume. Conversion between units will depend on what the two units are.
How many formula units are contained in 1.34g CaO?
To calculate the number of formula units in 1.34g of CaO, we first need to find the molar mass of CaO. CaO has a molar mass of 56.08 g/mol. Next, we convert the given mass to moles using the formula: moles = mass / molar mass. Finally, we use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
