It will calculate the total mass along with the elemental composition and mass of each element in the compound. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. You can use parenthesis () or brackets ...

对了,还有字符串的长度n,可以通过strlen()函数来取得。 doublesum=0;//每组分子串的开始时候分子量清零doublet=0;//用来暂存单个分子量的和intcnt=0;//用来记录连续数字字符的值 ——即分子个数intn=strlen(s);//记录分子串长度 接下来就要从字符串头开始循环到结尾来查找对应的是字母还是数字。 for(inti=...
UVA 1586 - Molar mass(思维) 题目大意: 输入一个n表示有n组数据,对于每一组数据输入一串化学式,求分子质量,这里只有4分子:C N O H 对应的:12.01 1.008 16.00 14.01 最后输出分子质量。 解题思路: 遇到分子就把他后面的数字字符串转换为数字和分子质量相乘,如果没有数字则默认为1个,这里用字符流转换一下...
n. 1.Also calledmo′lar tooth`.a tooth having a broad biting surface adapted for grinding, being one of 12 in humans, with 3 on each side of the upper and lower jaws. adj. 2.adapted for grinding, as teeth. 3.pertaining to such teeth. ...
where NW is the number of water molecules per unit cell (46 for Type I, 136 for Type II, and 34 for Type H), MW is the molar mass of water, Yij is the fractional occupancy of cavities of type i by component j, νi is the number of type i cavities, n is the number of cavit...
The viscosity average molar mass M¯v is obtained directly from solution viscosity measurements. The parameter “a” depends on the nature of the solvent (see Chapter 5) hence the solvent and temperature used for its measurement. Typically, M¯n<M¯v<M¯w while in a good solvent, a...
4). However, the rate of polymerization (86% conversion after 96 h ((Me)2TPL):(Et3N):(BnSH) = 200:1:1) proved too slow for the efficient synthesis of high molar mass samples. This is most probably a result of an equilibrium proton exchange between the active anionic chain end...
This paper provides a brief history of the molar mass of dry air, Mda, followed by the composition of Earth's atmosphere for the year 2008 and the calculation of Mda. A single equation is given to calculate Mda based on the actual abundance of CO2 in the atmosphere, which is currently ...
