How do you find water by mass in a compound?
To find water by mass in a compound, you can calculate the difference in mass before and after heating the compound to drive off the water. The lost mass represents the mass of water present in the compound. You can then calculate the percentage of water in the compound by dividing the mass of water by the total mass of the compound and multiplying by 100.
How many molecules of water are there in 1.802 grams of water?
To calculate the number of water molecules in 1.802 grams, first find the molar mass of water (H2O = 18.015 g/mol). Then, divide the given mass by the molar mass to get the number of moles (1.802 g / 18.015 g/mol = 0.1 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of water molecules (0.1 mol * 6.022 x 10^23 molecules/mol = 6.022 x 10^22 molecules).
What is the mass of 3.97x1021 molecules dinitrogen tetraoxide?
To calculate the mass of 3.97x10^21 molecules of dinitrogen tetraoxide, you first need to find the molar mass of dinitrogen tetraoxide (N2O4), which is about 92.02 g/mol. Then you can use Avogadro's number (6.022x10^23 molecules/mol) to convert molecules to moles and then multiply by the molar mass to find the mass.
When you calculate the mass of borax needed to make up the standard solution do you include 10H2O?
No, when calculating the mass of borax needed for a standard solution, you only consider the anhydrous (water-free) form of the compound. The water molecules incorporated in the crystal structure are not included in the calculation of the mass.
What would be the Mass of 3 moles of ammonia and calculate the number of ammonia molecules?
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.
What is the amount of H2O molecules in 20g of CuSO4.5H2O?
To find the number of water molecules in 20g of CuSO4.5H2O, we first need to calculate the molar mass of CuSO4.5H2O. The molar mass of CuSO4.5H2O is 249.68 g/mol. Then we can use the molar mass of CuSO4.5H2O to find the number of moles in 20g. Finally, as there are 5 water molecules in one formula unit of CuSO4.5H2O, we can calculate the number of water molecules corresponding to 20g of CuSO4.5H2O.
What is the percentage of water to the nearest tenth in this compound BaOH2 8H2O?
The compound Ba(OH)2·8H2O has 8 water molecules associated with it. To find the percentage of water in the compound, calculate the molar mass of the water molecules (8H2O) and the molar mass of the entire compound (Ba(OH)2·8H2O). Then divide the molar mass of the water by the molar mass of the entire compound and multiply by 100 to get the percentage of water.
Sulfur trioxide can react with atmospheric water vapor to form sulfuric acid that falls as acid rain. Calculate the mass in grams of 3.65 1020 molecules of SO3.?
To calculate the mass of 3.65 x 10^20 molecules of SO3, first calculate the molar mass of SO3 (80.06 g/mol). Next, convert the number of molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol). Finally, use the molar mass to convert moles to grams. Mass of 3.65 x 10^20 molecules of SO3 = (3.65 x 10^20 molecules / 6.022 x 10^23 molecules/mol) * 80.06 g/mol ≈ 0.49 g.
How can you demonstrate ther is space between molecules of water?
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.
Does ice molecules has less mass than water molecules?
no it has more
How do you calculate the percent water in a hydrate?
To calculate the percent water in a hydrate, you first determine the mass of water in the hydrate by subtracting the mass of the anhydrous compound from the mass of the hydrate. Then, divide the mass of water by the total mass of the hydrate and multiply by 100 to get the percentage.
How do you find water by mass in a compound?
To find water by mass in a compound, you can calculate the difference in mass before and after heating the compound to drive off the water. The lost mass represents the mass of water present in the compound. You can then calculate the percentage of water in the compound by dividing the mass of water by the total mass of the compound and multiplying by 100.
What is the mass in grams of 3.41x10e26 molecules of water?
first you divide by avagadro's number to get the number of moles. 3.41x10^26 / 6.022x10^23 = 566.25 moles The molecular mass of water is 18. moles is mass/molecular weight so moles by the mass is the weight. 566.25*18 is 10192.63g. This is 10.193kg. Are you sure your molecule count was not exponentially lower?
How many molecules in aluminum phosphate?
To calculate the number of molecules in aluminum phosphate, we need to know the mass of the sample. Given the mass of aluminum phosphate, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules in the sample.
