<p>这就是你要找的吗?
我认为问题出在整除和附加上</p>
<pre><code>import numpy as np
MolWeight = [132.0, 320.0, 29.0, 45.0, 10.0]
Ci = 10.0 # g/L initial Concentration
Cf = 50*10**(-6) #M final Concentration
Vf = 100*10**(-6) #Litre final Volume
Vi = []
for i in range(len(MolWeight)):
#How many moles of the compounds are there in the standard solution
Mi = Ci/MolWeight[i] #M
#this corresponds to the initial concentration of the standard compound
Ci = Mi # M/L
#I calculate the volume to extract from the standard compound solution, so to obtain the desired concentration
# np.append.Vi[i] = (Cf * Vf) / Ci # L
Vi.append((Cf * Vf) / Ci )
print Vi
</code></pre>
<p>输出</p>
