常用化学计算公式
1、物质的量n与微粒个数N、质量m、气体体积V、物质的量浓度C、反应热∆H的关系：
n = N/NA = m/M = V/Vm = CV = ∆H/∆H1 (∆H1是指1mol物质放出的热量）
2、克拉珀珑方程又称理想气体的状态方程：
PV = nRT
3、溶解度S与溶质质量分数ω的关系：
ω = S/(100+S) * 100%
4、物质的量浓度C与溶质质量分数ω的关系：
C= 1000*d*ω/M
5、有关气体摩尔质量的计算：
M = m/M = ρVm = DM2 = m0NA= M1ω1 + M2ω2 + M3ω3 ....
( D指相对密度; m0指一个分子的质量；ω指n% V%)
6、溶液稀释定律：
m1ω1 = m2ω2 C1V1 = C2V2
7、密度和相对密度：
ρ = m / V D = ρ1/ρ2 = (M1/M2)
8、 化学反应速率：
ν = ∆C / ∆t = ∆n /(V.∆t)
9、化学平衡计算：
可逆反应： a A + b B <=> c C + d D
起始量（mol） a b c d
变化量（mol） mx nx px qx
平衡量（mol） a-mx b-nx c+px d+qx
10、水的离子积：
Kw = C(H+)•C(OH-) =(常温250C时）10-14
注：任何水溶液中，由水电离出的H+和OH-都相等。
11、溶液的PH:
C(H+)=10-pH 常温下 PH + POH = 14
12、溶度积Ksp ：
以MmAn(s) mMn+(aq) + nAm－(aq)为例
Ksp＝[c(Mn+)]m•[c(Am－)] n
如AgCl(s) Ag+(aq) + Cl－(aq)，Ksp＝c(Ag+)•c(Cl－)。
13、化学平衡常数
对于一般的可逆反应mA(g) + nB(g) pC( g)+qD （g）
K = {[C(C)]p [C(D)]q }/{[C(A)]m [C(B)]n }
祝你学习进步！

这个我不能说答案，这个只能靠自己的思维来抢，这个也是里头的，你可以根据你特物理数学公式来计算，你就会这个化学的基本公式，这差不多也跟这个数学物理也是一样的道理，懂得吧？
