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 H2SO4contains hydrogen (H), sulfur (S...
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...
either 1 to a given number (such as 1:64) or in terms of ounces per gallon (2 ounces per gallon). If you need to calculate the ounces per gallon remember that there are 128 ounces in a gallon, so a 1 ounce per gallon product dilutes at a ratio of 1:128 and ½ and ¼ oun...

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 ...
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...
