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 ...
40 grams ofNaOHin 1000 mL of water equals how many equivalent(s) ofOH−? a. 23 b. 17 c. 3 d. 1 e. 40 Equivalents: For bases as well as acids, the count of moles of hydroxide or hydronium ion liberated upon dissolution is called equivalents. It is calculated...
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{+}: ElementNumber of Atoms Na(Sodium)1 O(Oxygen)1 H(Hydrogen)1 e(Electron)-1 Because the molecule has a positive charge, we need to subtract the...
How many moles are in 13.8 grams of NaOH?Molar Mass:Molar mass is equal to the mass of one mole of a substance. The molar mass is usually used to convert the mass of a substance into moles and vice versa.Answer and Explanation: ...

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[ ]。
Answer to: Determine the concentration of a 25.0 mL sample of NaOH (aq) if it requires 16.9 mL of 0.450 M H_2SO_4 (aq) to reach the stoichiometric...
Molar amount of functional groups in 1 g lignin (mmol/g) 0.70 0.03 0.32 0.07 1.44 Note: Assume that the total mass of acetylated lignin is 1.0 g, then the acetylated AL containing lignin: MAL = 1 − (0.07 + 1.35) × 10−3 × 42 = 0.940. Tabl...
