equationsinstead of units of mass or volume as a more appropriate way to express reactants or products in chemical reactions. Mole is a conversion number that allows chemists to move from the microscopic world of atoms, molecules, and ions to the macroscopic world of grams, kilograms, and ...
We often need to calculate the mass of a substance present in a solution of known concentration and volume. To do this we: ■ rearrange the concentration equation to: number of moles (mol) = concentration (mol dm–3) × volume (dm3) ■ multiply the moles of solute by its molar mass ...

Divide the given mass (25.0 g) by the molar mass (158.032 g/mol) to get the moles. The number of moles of KMnO4 will be 0.158 And here is how you should enter this problem into the calculator above:grams to moles problem solution ...
We examined regression statistics from both the shrews and moles, and these appeared to fit the conventional allometric equation (log(y) 5 log (b) 1 m[log(x)] or y 5 bxm, where y is average brain mass and x is average body weight. The slope m for the brain-body weight regres- ...
If the mass of nail used was 1.45g, calculate the number of moles of Fe2+ produced in the reaction.The solution they gave was simple:5 x (4 x 10-4) x 10= 0.02 mol.But I don't understand. If 1 mol of MnO4 requires 5 mol of Fe2+, wouldn't it mean that 1 mol of Fe 2+ ...
