Multiply the volume of the liquid oxygen by its density, 1.14 g/ml, to calculate the mass of the compound. In our example, the mass of oxygen is 70,000 ml x 1.14 g/ml or 79,800 g. Step 3 Divide the mass of oxygen by its molecular mass to calculate the number of moles. In our...
Chemical oxygen demand, or COD, is a test that measures the amount of organic compounds in water. More specifically, the test is a process of decomposing pollutants in water after two hours of boiling the water in a solution of potassium dichromate. If the COD is high, the amount of pollu...
Here is how to calculate how much water you should drink a day for both health and weight loss benefits. Your weight: The first step to knowing how much water to drink every day is to know your weight. The amount of water a person should drink varies on their weight, which makes sense...

City air contains a certain concentration of benzo[a]pyrene - select a city to obtain an average concentration of benzo[a]pyrene in this location. The air indoors contains about 10% fewer harmful substances. From the above data, you can calculate how much b[a]p an adult inhales per day...
Total Carbon (TC) = TDW × 0.5 With the value of total carbon, we can calculate the value of CO2equivalent sequestered on a tree. CO2has one molecule of Carbon and two molecules of Oxygen. The atomic weight of Carbon is 12u, and the atomic weight of Oxygen is 16u. The weight of ...
The detected intensities from the mass spectrometer were calibrated by linear regression, and then the equation of the calibration curve was used to calculate concentrations of dissolved ions in the electrolyte. The dissolution rate of Al is converted by subtracting the solute contribution from the ...
To calculate the amount of chloride physically bound in C-A-S-H, one needs to determine the C-A-S-H content, which can be very challenging in blended cement systems without relying on complex hypotheses (e.g., the amount of water in the C-A-S-H, the incorporation of guest ions, ...
Calculate the enthalpy in the water vapor by plugging the water content of the air (in kg per kg) and the air temperature into the following formula: Water vapor enthalpy = water content of air x (2501 + 1.84 x temperature). Consider air that has a water content of 0.01 kg per kg of...
Here’s how to calculate the amount of oxygen absorbers you should add:↓ Selecting the Proper Oxygen Absorber Size For StorageIf done right, your rice will no longer be exposed to any oxygen.And since mold cannot grow without it, your rice becomes safe from spoilage.Also, if you want to...
