Choose a reference point outside of the object you want to calculate the center of mass for. This point is arbitrary but should be reasonably close to the object. Step 2 Multiply the mass of the object (M) by the distance between the object and the reference point (R). Using the above...
The first step in calculating mass properties of an object is to assign the location of the reference axes. The center of gravity and the product of inertia of an object can have any numerical value or polarity, depending on the choice of axes that are used as a reference for the ...

要计算给定物质的质量中所含的摩尔数，首先需要知道该物质的摩尔质量。摩尔质量是物质的相对分子质量，单位为克/摩尔（g/mol）。以水（H₂O）为例，其摩尔质量为18.015 g/mol（2×1.008 g/mol for hydrogen + 15.999 g/mol for oxygen）。使用摩尔质量，可以通过以下公式计算物质中含有的...
Re: How do you calculate the molar mass? « Reply #1 on: February 18, 2008, 01:11:37 PM » Mikey, I will say that 8H2O is part of the composition and you should threat like that! the rest of the calculations is yours, I can write the whole process but the rules says that ...
For this reason, when you calculate your mass on a scale designed for use on Earth, weight is already factored into the operation of the scale. Mass is not weight, but they are always directly proportional to each other by the value of g, whatever it may be. ...
Subtract your lean body mass from your total body weight to calculate your body fat mass. Continuing with the example, 180 minus 141.1 calculates your body fat mass of 31.9 pounds. Divide your body fat mass by your total body weight and multiply by 100 to calculate your percent body fat. ...
Calculate the volume of a sphere by cubing the radius, multiplying this number by π or pi and then multiplying that product by 4/3. For example, if the radius is 2 cm, cube 2 cm to get 8 cm^2; multiply 8 by π, to get 25.133; and multiply 25.133 by 4/3 to get 33.51. So,...
Another way to calculate the weight to volume ratio of an object is to use the density formula. The calculation is not too complicated as you only need to do one operation to find it. The density formula is as follows: D=m/vD=m/v where: DD - density; mm - mass; and vv - volume...
Calculating mass ratios is easy enough if you have access to a periodic table (see Resources) and the means to do basic algebra. Say you want to calculate the mass ratio of sulfuric acid, H2SO4. 1. Determine the Molar Mass of Each Element Present ...
