A few tweaks to your code is all that’s necessary:
C = {randi(50,1,6)  randi(50,1,5)  randi(50,1,7)};  % Create data
fprintf('\nconcentration is ')
for j=1:length(C)
        fprintf(' %d ',C{j})
end
fprintf('\n')
produces:
concentration is  6  25  48  18  30  12  38  13  26  35  45  48  28  7  8  13  43  13
Is that what you want?
