Your program is to write to standard output. Print exactly one line for each test case. The line should contain the molar mass of the given molecular formula. Sample Input 4 C C6H5OH NH2CH2COOH C12H22O11 1. 2. 3. 4. Sample Output 12.010 94.108 75.070 342.296 1. 2. 3. 分子量 给出...
The lowest such ratio is then said to give the empirical formula for the compound. If the molar mass of a compound is known, its molecular formula can be determined by multiplying the elements by a factor that is given by the molar mass o...
Anionic polymerization of propylene oxide was carried out in the presence of two groups of potassium salts activated 18-crown-6 (18C6), e.g. alkoxide salts (CH3OK, i-PrOK, t-BuOK, CH3OCH2CH(CH3)OK, KCH2O) and other salts (CbK, Ph3CK, Ph2PK, Ph3HBK, KK, KH, and [(CH3)(3...
The variations of the excess molar volumes for these mixtures followed a similar decreasing trend, with contractions observed in the systems consisting of high molar mass esters and lowestn-alkanes. These effects have been interpreted on the basis of molecular interactions. The UNIFAC, DISQUAC, and...
