Can we assume that these two storage containers are filled to complete capacity? That makes the second container have 3 volume parts and the first container having 2 volume parts.

To see for sure, v%2A%281.50%29=%283%2F2%29v.

First Container     2v       30% acid
Second Container    3v       50% acid


The mixture of all of this is in the third container. Two parts plus three parts is 5 parts for the mix volume.

%282%2A30%2B3%2A50%29%2F5

%2860%2B150%29%2F5

210%2F5

42
42 % Acid, mixture
