# Volume of water Volume = (Weight of conical flask + water) / (Density of water) * From the value obtained is noted down as volume correction. * Calibration of measuring flask of 250 ml and 100 ml. * A 250 ml conical flask is weighed with distilled water. * The water is adjusted to the zero reading of lower miniscule and the weight of the measuring flask is also noted down. * Mass of the empty dry measuring flask = M1 gm * Mass of measuring flask + water = M2 gm * Mass of water = M2 - M1 * Density of water according to lab temperature = ______ * Volume of the water = Weight of water / Density of water # Digital Electronic Weighting balance: * A digital electronic weighing balance of 0.001/0.000 precision value is used for weighing solid substances (or) chemicals for various laboratory experiments. * First in the electronic balance, 'ON' button should be pressed and wait for a few seconds, it will show zero '00' seconds on the digital reading. * If 'O' displays is not shown then gently press 'TARE' to ensure reading to come to zero 'o'. * Always use weighting bottle /watch glass on light weight beaker to weigh any liquid /solid substance. * After number of times weighting the weighing bottle containing the particles of other chemical substance present in it - Use a filter paper to clean the inner side of weighing bottle and ensure all the particles are removed carefully. * Now weight the empty weighing bottle and press 'TARE' to get zero 'O' on the digital reading.
