How many grams are in 3 mole of KBr?
Easy...the periodic table gives the average mole weight of each element averaged out over all it's naturally occurring, if any, isotopes, i.e., K is 39.09 Br is 79.9 Add them up and it's (to three significant figures): So KBr is 119 g/mole
How many moles of k are needed to form 3.3 moles of KBr?

How many grams does 3 moles of CO2 weigh?
Atomic mass of C = 14g/mol Atomic mass of O = 16g/mol Molecular mass of CO2 = 12 + 2(16) = 44g/mol mass = number of moles x molecular mass mass = 3 mol x 44g/mol = 132g
How many grams are in 3 moles of lithium?
to get the answer just take number of moles you have and multiply it by the molecular mass of the compound which is 22g/mol in lithium oxide's case. 23mol x 22g/mol = 506 g of Li2O
The formula for ammonia is NH3 the mass of 3 moles of ammonia would be how many grams?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
How many grams 3 of HF?
The molar mass of HF (hydrofluoric acid) is 20.01 g/mol. Therefore, 3 moles of HF would be equal to 60.03 grams.
How many grams are there in 3 moles of CuSO4?
The molar mass of CuSO4 is 159.6 g/mol. To find the mass of 3 moles of CuSO4, multiply the molar mass by the number of moles: 3 moles * 159.6 g/mol = 478.8 grams. Therefore, there are 478.8 grams in 3 moles of CuSO4.
If formula for ammonia is NH what is the mass of 3 moles of ammonia would be in grams?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
What is the mass of 3 mol of Al?
As the periodic table of Elements states, Al has a Molar Mass (Grams/Mole) of 27.0g/mol. So 3 mols of Al mass is the same as 3 times 27.0g/mol. So, the equation is as follows: 3mols x 27.0g/mol = 81.0g. The reason on why it ends with grams is because the unit of moles in 3 will cancel out with the unit of mols in 27.0g.
How many grams of NH 3 can be produced from 3.13 mol of N 2?
To determine how many grams of NH₃ can be produced from 3.13 mol of N₂, we start with the balanced chemical equation: N₂ + 3H₂ → 2NH₃. From the equation, 1 mole of N₂ produces 2 moles of NH₃. Therefore, 3.13 moles of N₂ will produce 3.13 × 2 = 6.26 moles of NH₃. To convert moles of NH₃ to grams, we use its molar mass (approximately 17.03 g/mol): 6.26 mol × 17.03 g/mol = 106.36 grams of NH₃.
How many grams of aluminum chloride does it take to make 0.88 mol of ZnCl2?
To make 0.88 mol of ZnCl2, you would need an equal molar amount of AlCl3. The molar ratio between AlCl3 and ZnCl2 is 2:3. Therefore, you would need 0.88 mol * (2/3) = 0.59 mol of AlCl3. To convert this to grams, you would multiply by the molar mass of AlCl3.
Mass of 3 moles of ammonia would be?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
