1.1.032*10^4 = 120n - 18(n-1)
n = 101
101 * 6 *300 = C;
----------------------------------------------------------
2.4*10^4 = 110n - 18*(n-1)
n = 434(这里出小数了,但它说,分子量大约为4*10^4D,我也就约了)
434*6 = 2604
2604*700 = 1822800(这题没什么把握)
----------------------------------------------------------
3.51 * 6 = 306;
306/2 = 153 153*300 = 45900
51*90 - (51-2)*18 = 3708
