The molecular weight of CuBr = (63.5 + 79.9) = 143.4 g/mol.
143.4 g/mol * 500 mol = 71700 g CuBr.
The mass of sulfuric acid is 490,395 grams.
16 grams of oxygen how many moles is 0,5 moles.
The molar mass of oxygen is 16 g/mol. To find the weight of 1.8 moles, you would multiply the number of moles by the molar mass: 1.8 moles * 16 g/mol = 28.8 grams. Therefore, 1.8 moles of oxygen weighs 28.8 grams.
1,8 grams of fluorine is equivalent to 0,0947 moles.
0.377 grams of Kr is equal to 0,0045 moles.
The mass is 27,576 g.
In order to figure this out, you must do dimensional analysis. Here it is: 3.0 moles He x 4.0026 grams/ mole He = 12 grams
The mass of sulfuric acid is 490,395 grams.
16 grams of oxygen how many moles is 0,5 moles.
2.2 moles of NaOH weigh 99.55 grams. This is calculated by multiplying the number of moles by the molar mass of NaOH, which is 40 grams per mole for Na (22.99 g/mol) + O (16.00 g/mol) + H (1.01 g/mol).
By stoichiometry, 2 moles of sodium carbonate will produce 2 moles of sodium chloride. The molar mass of sodium chloride is approximately 58.44 g/mol, so 2 moles would weigh about 116.88 grams.
To find the grams of CuFeS2 in 3.95 moles, you need to know the molar mass of CuFeS2, which is approximately 183.5 g/mol. Therefore, 3.95 moles of CuFeS2 would be 3.95 moles * 183.5 g/mol ≈ 724.325 grams.
The molar mass of oxygen is 16 g/mol. To find the weight of 1.8 moles, you would multiply the number of moles by the molar mass: 1.8 moles * 16 g/mol = 28.8 grams. Therefore, 1.8 moles of oxygen weighs 28.8 grams.
53 grams ÷ 18.01 grams/mole = 2.94 moles
The molar mass of sodium is approximately 23 grams per mole. Therefore, 2 moles of sodium would weigh around 46 grams.
120 grams of calcium contain 2,994 moles.
1,8 grams of fluorine is equivalent to 0,0947 moles.
