Use your mass of water and the volume of the volumetric pipet to calculate the density of water for each trial. Calculate the average density‚ standard deviation‚ and the 90% confidence limits for the average density. 9- Use the temperature of your water along with the values of mass and volume of water given in Table I to calculate the accepted values for the density of water.

system. The first unit in the T-Dog system is “Sweats” ( )‚ a measurement of temperature. This measurement was invented by the unique Talha Tribe‚ who were the first ones to employ the use of this ingenious system. This measurement is used to calculate and measure heat‚ specifically the temperature of any given atmosphere‚ and depict the weather. This measurement is based on the amount of sweat one produces under a given amount of heat; therefore this unit was given the name “Sweats”. The symbol
