disco ball jewelry wholesale The results of the calculations are different, and the data that needs to be measured is different.
The first method: The formula of the hanging water method The formula for detecting the golden color is: the weight of gold in the air ÷ the weight of gold in water ÷ 19.32 = gold. Determine the purity of gold by using the important differences between gold and the air in water and air.
The second method: gold density = gold quality ÷ the volume of gold. This method is to determine the purity of gold by calculating the density of gold.
both methods are common methods. However, the difference is that the method only needs to calculate the two sets of weight data, and the method 2 needs to calculate the volume and quality to calculate the density, comparing the purity of gold. The latter method errors are relatively large, so the purity of gold is used to measure the purity of gold.
