这个程序决定一种物质的分子量。输入物质的分子式,它将计算出元素的组合物和质量的化合物中的每个元素的总质量。 元素中的第一个字符使用大写字母,第二个字符使用小写字母。例子:Fe, Au, Co, Br, C, O, N, F。 你可以用小括号()或括号[ ]。
The first step to finding the molar mass is to count the number of each atom present in a single molecule using the chemical formula, NaOH + HB + H2O: ElementNumber of Atoms Na(Sodium)1 O(Oxygen)2 H(Hydrogen)4 B(Boron)1 2. Find Atomic Mass of Each Element ...
What is the molar mass of NaOH?How to Calculate Molar Mass:Looking at the periodic table of elements, molar mass is the number below each element. It is given in grams per mole (grams / mole), where 1 mole is 6.02 x 102 atoms of said element. In other words, molar mass of an ...
