The Loss on Drying (LOD) formula for solid powder forms is typically calculated as: LOD (%) = ((Initial weight - Final weight) / Initial weight) x 100 Where: Initial weight is the weight of the sample before drying. Final weight is the weight of the sample after drying.
To determine the density of a granular substance that is insoluble in water, you can use the method of displacement. Fill a graduated cylinder partially with water and record the initial volume. Carefully add the granular substance to the water, making sure it doesn't dissolve. Record the final volume, and calculate the volume of the substance by subtracting the initial volume from the final volume. Finally, divide the mass of the substance by its volume to determine its density.
The k-factor for explosives is typically determined experimentally by measuring the pressure generated by a known quantity of explosive in a confined space. The k-factor is the slope of the pressure-time curve on a semi-log plot and is used to relate the energy released by the explosive to the pressure generated. It is an important parameter for designing blast mitigation measures and can vary depending on the type of explosive and its properties.
To determine molecular weight using the Landsberger method, you would prepare a calibration curve by plotting the retention time of known molecular weight standards versus their molecular weights. Then, you would measure the retention time of your unknown sample under the same conditions and use the calibration curve to determine its molecular weight. The molecular weight of the unknown sample can be calculated using the equation of the calibration curve.
Calibration using an internal standard involves adding a known amount of a standard substance to the sample before analysis. By comparing the response of the analyte to the internal standard, you can account for variations in sample preparation, instrument performance, and environmental conditions. This allows for accurate quantification of the analyte in the sample.

The ratio of the perimeters is equal to the scale factor. If rectangle #1 has sides L and W, then the perimeter is 2*L1 + 2*W1 = 2*(L1 + W1).If rectangle # 2 is similar to #1 and sides are scaled by a factor S, so that L2 = S*L1 and W2 = S*W1, the perimeter of rectangle #2 is 2*(L2 + W2)= 2*(S*L1 + S*W1) = S*2*(L1 + W1) = S*(perimeter of rectangle #1).
- for example, two women (w1 and w2) and a man. the man is married to w1. the man goes after w2 making her think that he is single. man and w2 becomes bf/gf then later w2 finds out that the man is married with w1. can w2 say that she was cheated on? obviously the man cheated with w2, but if w2 didn't know that the man was married to w1, can w2 actually say she was 'cheated on' considering the fact that she was the 'other woman' and that w1 was established first.
