You can calculate weight loss as a percentage of your total body weight. Here's how to calculate weight loss percentage and why it matters.
the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this for both substances to let you calculate the final concentration of the solution. (Remember
Molar mass is related to mass percentage, and it is used to calculate the ratio between the mass of a certain quantity of a substance to the number of moles of that substance. It is similar to a density value. To calculate the the molar mass of the compound, we take the mass of solu...
Describe the probable cause of this problem and explain what steps might be taken to increase the recovery. Explain the steps to calculate strain energy using your own example. What is the percentage composition of PbCO_3? What is the rule to find the percent error in the experiment? Why ...
How to Calculate Molarity of a Chemical Solution Yucel Yilmaz / Getty Images Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution,...
Enter the weight/mass of the object. To enter the mass in a different unit, click on the unit and change it before entering the value. Input the volume of the object. If the object is a cuboid, and you know its dimensions instead of the volume, click on the Calculate volume section ...
Find the percentage error the approximation (sin theta - theta)/theta introduces for an angle of 0.020 radians. In the examples below, the measurements of a and b are used to calculate the product q = ab. Calculate both the quantity q with error, and calculate the percent e...
You can perform a PPM conversion easily provided you have two quantities in the same unit (or that you can convert into the same unit) or a percentage value. PPM means "parts per million," so to calculate it you divide the amount of the solute by the tot
