Ar of N = 14g/mol
Ar of O = 16g/mol
Mr of N2O5 = 2(14)+5(16) = 108g/mol
Using the formula : number of moles = mass / Mr
number of moles = 1296g / 108g/mol = 12mol
Each mole of substance contains 6.02 x 10^23 particles, therefore 1296g of N2O5 contains 12 x 6.02 x 10^23 = 7.224 x 10^24 molecules.
To find the number of molecules in 1296 g of dinitrogen pentoxide (N2O5), first calculate the molar mass of N2O5 which is 108 g/mol. Then, divide the given mass by the molar mass to get the number of moles (12 moles). Finally, use Avogadro's constant (6.022 x 10^23) to convert moles to molecules, giving approximately 7.2 x 10^23 molecules.
Well first things first you have to balance the equation Fe3O4-->3Fe+2O2 Then because your given mass is in kg you have to convert it to grams 100.0kgx1,000kg/(over)1g=100,000g or 1.0x105 Next because you have mass of Fe3O4 you need to get the molar mass. (3)55.85gFe+(4)16.00gO=231.55gFe3O4 Now convert grams to moles for your final answer 1.0x105gFe3O4x1mol/(over)231.55g(mm)x3molFe/(over)1mol Fe=1295.6 mol Fe you can recover 1295.6moles of Fe from Fe3O4 If you follow the rule of Significant Figures, 100.0kg has 4 significant figures (digits) so your answer needs to have 4 digits 1295.6=1296 you can recover 1296 moles of Fe from Fe3O4
The boiling point of water decreases as elevation increases, so near the Dead Sea, which is below sea level, the boiling point would be slightly lower than at sea level. Therefore, the cooking time for pasta would be slightly longer near the Dead Sea compared to cooking at sea level due to the lower boiling point of water.
