To find the number of moles in 63.0 g of (NH4)2Cr2O7, first calculate its molar mass. The molar mass of (NH4)2Cr2O7 is approximately 252.13 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), we find that the number of moles is 63.0 g / 252.13 g/mol ≈ 0.249 moles.
The number of moles 9,92.10e-5.
978 g calcium contain 24,4 moles.
29,0 g of calcium is equal to 0,723 moles.
67,4 g HCl is equivalent to 1,85 moles.
14,84 g magnesium are equivalent to 0,61 moles.
The number of moles 9,92.10e-5.
The molar mass of NH42Cr2O7 is 272.32818 g/mol
630 g = 0.63 kgTo convert from g to kg, divide by 1000.
1 g = 1000 mg 630 mg = 0.63 g
The formula is: number of moles = g Be/9,012.
14,84 g magnesium are equivalent to 0,61 moles.
97,5 g of oxygen is equal to 5,416 moles.
978 g calcium contain 24,4 moles.
67,4 g HCl is equivalent to 1,85 moles.
29,0 g of calcium is equal to 0,723 moles.
573,28 of g of AgCI is equivalent to 4 moles.
27.4 g H2O x 1 mole/18 g = 1.52 moles
