解析 We don't round it to a whole number because we want the number of the relative atomic mass of cholorine to be as precise as possible.We really care about the significant figures,so it's better if we get more digits. 结果一 题目 why is this the relative atomic mass of chlorine ...
What is the atomic number for chlorine? How many protons are in chlorine? How many neutrons are in chlorine? What is the gram molecular mass (gmm) of chlorine? What is the density of chlorine gas? How many atoms of chlorine are in 2.00 mol of chlorine gas?
How many electrons does chlorine have? What is an oxidation state? What is oxidation in organic chemistry? What is a transition metal that always has a +1 oxidation number? What is the mass number of chlorine? What is the oxidation number of potassium in KMnO4?
We don't round it to a whole number because we want the number of the relative atomic mass of cholorine to be as precise as possible. We really care about the significant figures, so it's better if we get more digits.

The number of protons and electrons is the subscript (6). To find the number of neutrons use the following equation: #neutrons+Z=massnumber Plugging in what you know yields: #neutrons+6=13 So: #neutrons=7 Carbon-13 has seven neutrons while carbon-12 has six. ...

To find the number of moles of sodium chloride (NaCl) in 585 grams, we can follow these steps:Step 1: Determine the molar mass of sodium chloride (NaCl). - Sodium (Na) has an atomic mass of approximately 23 g/mol. - Chlorine (C
Number of Avogadro In subject area: Engineering The word ‘mole’ has been adopted to represent the Avogadro number of atoms of an element, that is, the relative atomic mass of an element. From: Newnes Engineering and Physical Science Pocket Book, 1993 About this pageAdd to MendeleySet alert...
溴是将“atomic number 35"翻译成 中文。 译文示例:For example, the relative atomic mass of chlorine is 35.453 u, which differs greatly from a whole number as it is an average of about 76% chlorine-35 and 24% chlorine-37. ↔ 數值可能是一個分數,例如氯的相對原子量為35.453,不太接近整數...
