      You may be looking for something like this: 

      ...
print "Please enter RNAi name, concentration, volume:  (empty line to 
+continue)\n";

while ((my $line = <STDIN>) ne "\n") {
    chomp $line;
    my ($name, $conc, $vol) = split ' ', $line;  # split by whitespace

    $RNA{$name} = $conc;
    $vol{$name} = $vol;
}
...
