... measure the volume. From that point its mass and volume are divided to give you the density of the solid. To find the mass of a liquid you must first measure the container that you are going to put the liquid in. Put the liquid in the container and find the measurement. Subtract the weight of the container and you will have the mass of the liquid. The volume of a liquid can be determined by something as simple as a measuring cup used for cooking ... . 6. Record the volume of the stopper. 7. Now by using the density formula D=m/v you will get the density. An example of finding the density...

... detached the rubber tube form the flask we tighten the stopper and determined the mass of the stoppered flask and CO2 gas. After determining the mass we immediately determined the temperature of the CO2 by inserting a thermometer in the flask. During this time I recorded the barometer reading in mm. Last of all we filled the flask with water to the bottom of the stopper, and measured the volume of the water by transferring it into a graduated cylinder. The water represents the original amount of the air ... Accepted molar mass of CO2 44.0 g CO2 Error in the molar masses of CO2 .6 g CO2 ...

... an error with the thermometer) - Mass of MgSO4 and MgSO4•7H2O (error on the electronic balance) - Specific Heat Capacity (we are using the specific heat capacity of water) - Volume of Water - this is the controlled variable, as we will use the same amount of water in each experiment. - Water may have impurities (but we will use distilled water to decrease the error here) Equipment: Distilled Water Measuring Cylinder Polystyrene cup with ... As we can not measure this enthalpy change directly, we will use the following two equations to calculate the enthalpy change for the equation abo...
