How to use a balance to find the mass of an object? Explain. Measurement: Measurement is a way to determine the magnitude of a desired trait of a given object. These traits include the mass of an object, the volume of an object, temperature, and time. Answer and Explanation: 1...
Calculate the volume of the substance by dividing the mass of the substance by the density (volume = mass/density). Ensure the units are kept constant during the calculations. Pay attention to the units of measure to ensure an appropriate result. For example, if the density is given in kg ...
While it is important to understand moles and the number of atoms and molecules, a more practical unit for experiments is the gram, which is a unit of mass. You cannot measure a mole of a substance in a laboratory, but you can measure its mass in grams on a balance. The conversion fa...
Understand how to use the formula to find the molality of a solution and molality from density. Related to this QuestionHow many grams of CaCl_2 are needed to prepare 6.00L of a 0.400M CaCl_2 solution? How many grams of CaCl_2 are needed to prepare 7.25 L of...
This is helpful since we needed to find the mass and we know the molecular mass of oxygen gas. If we substitute for n in the first equation, we get: V = (mRT)/(MMP) Divide both sides by m: V/m = (RT)/(MMP) But density is m/V, so flip the equation over to get: ...
HDL, high-density lipoprotein cholesterol, or the "good" one Triglycerides, fats carried in the blood from the food we eat Results of your blood test will come in the form ofnumbers. The numbers by themselves are not enough to predict your risk ofheartproblems or to determine what you need...
Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their

So if you have a volume of water with something dissolved in it, you’ll either need to use the volume of the other substance (i.e. the solute) too, or use the mass of both. Using the volume of the water but the mass of the solute would lead to a nonsensical result. ...
