Question regarding significant figures .. Following this conversion, would it be correct to have only 1 significant figure for the answer, because we have multiplied with (2 mol / 5 mol) which only has 1 sig fig. Could you confirm this calculation is correct in regards to the significant figures? 0.105 g Na2C2O4 * (1 mol / 134 g Na2C2O4) * (2 mol KMnO4 / 5 mol Na2C2O4) = 0.0003 --> 3x10-4 3*10-4 mol KMnO4 / 0.0312 L KMnO4 =...
