I have a simple question. If when mixing two liquids together the directions say mix 10.4 parts of hardner by weight for every 100 parts of resin and I want the final mixture to be 2.75lb, could I do the following? Mh = mass of hardener Mr = mass of resin Mh + Mr = 2.75lb Mh/Mr = 10.4/100 = .104 Then just solve from there to get the amount of each. I know this should be pretty straight forward but I just wantedto double check. Thanks in advance.
