Webmeasurement as 6.20 cm. However, the uncertainty, according to the rules above is 1/2 the distance between the smallest two marks, or 0.2/2 = 0.1. It doesn’t make sense to say 6.20 ± 0.1 cm because your uncertainty is so much bigger than the estimated digit (the zero). So, we need to go back to the most important idea of reporting uncertainties. WebKIO3 molecular weight. Molar mass of KIO3 =. This compound is also known as Potassium Iodate.
