Mass of 3 moles of ammonia?
Molar mass of ammonia = (14.01 + 3.03) (Molar mass of nitrogen + 3 times molar mass of hydrogen, as chemical formula of ammonia is NH3). Molar mass= 17.04 Molar mass x moles = mass 17.04 x 3 = 51.12 Mass of 3 moles of ammonia is 51.12g.
How much copper is present in 100g of copper sulphate?
You can answer this question using a molar mass calculation for CuSO4. 63.55 g Cu + 32.06 g S + 4(16.00 g O) = 159.55 g CuSO4 In 159.55 g CuSO4, there are 63.55 g Cu. Use this as a conversion factor. 100 g CuSO4 x 63.55 g Cu = 39.8 g Cu .................... 159.55 g CuSO4
Determine the mass of 21 mol N?
number of moles = mass/molar mass mass = number of moles x molar mass 21mol x 14gmol-1 = 294g molar mass of Nitrogen is 14, which you can find on a periodic table
What is the formula mass of CuSO4 x 5H2O?
The relative formula mass of CuSO4.5H2O is worked out from the following masses:Cu = 63.55S = 32.06O x 9 = 16 x 9 = 144H x 10 = 1 x 10 = 10Adding these up, we get a relative formula mass of 249.61, often rounded up to 250. This means that one mole of CuSO4.5H2O weighs 249.61g.
What is the formula for hydrated copper II sulfate?
Copper sulfatepentahydrate is a solid at 20 degrees Celsius has a density of 2.28g/cm3 (cubed)... and its' chemical symbol is CuSO4-5H2O
Find the percentage of water to the nearest tenth in crystal of CuSo4 x 5H2O?
56,25 percent
What is the percentage of water CuSO4 5H2O?
First of all, it's CuSO4*5H2O (notice the capital "O" in the first part of the formula). The compound is called copper(II) sulfate pentahydrate, and if we wish to find the percent by mass of water, we need to find the molar mass of the hydrate first. Cu = 63.55 g/molS = 32.07 g/molO x 4 = 16.00 g/mol x 4 = 64.00 g/molH2O x 5 = 18.02 g/mol x 5 = 90.10 g/molNow add them all together and you get a molar mass of 249.72 g/molOf that 249.72 grams, 90.10 grams is water, so to find the percentage by mass that is water, simply divide 90.10 g by 249.72 g and multiply the result by 100%:90.10 g / 249.72 g x 100% = 36.08% water
What is the equation for copper II chloride hexahydrate?
Cu(NO3)2 x 5H2O is the chemical formula for copper II nitrate pentahydrate.

You can answer this question using a molar mass calculation for CuSO4. 63.55 g Cu + 32.06 g S + 4(16.00 g O) = 159.55 g CuSO4 In 159.55 g CuSO4, there are 63.55 g Cu. Use this as a conversion factor. 100 g CuSO4 x 63.55 g Cu = 39.8 g Cu .................... 159.55 g CuSO4
Mass of a mole?
The molar mass of an element is its atomic weight in grams. The molar mass of a molecule or compound is the sum of the subscripts times the molar masses in grams. For example, the molar mass of hydrogen, H, is 1.00794g and the molar mass of oxygen, O, is 15.9994g. The molar mass of water, H2O, is (2 x 1.00794g) + (1 x 15.9994g O) = 18.01528g.
Determine the mass of 21 mol N?
number of moles = mass/molar mass mass = number of moles x molar mass 21mol x 14gmol-1 = 294g molar mass of Nitrogen is 14, which you can find on a periodic table
What is the molar mass of C4H8O4?
To determine the molar mass of a molecule, you need to determine the molar mass of each element from the periodic table, then multiply the molar mass by the subscript for the element in the formula. Do this for all of the elements in the formula and add them together to get the molar mass. The molar mass of an individual element is its atomic weight in grams. Molecular molar mass of C4H8O4 = (4 atoms C x 12.0107g/mol C) + (8 atoms H x 1.00794g/mol H) + (4 atoms O x 15.9994g/mol O) = 120.1039g/mol C4H8O4
What is a molar mass and what is it used for?
The molar mass is the sum of atomic weight of the atoms contained in a molecule. Example: water, H2O The molar mass is: 2 x 1,008 + 15,999 = 18,015 Molar mass is used in many calculus in chemistry.
