I am checking the accuracy of a titrator that is titrating 5% lactose in coulomat AG. The certified value of the standard being used (5% lactose) is 50.8mg/g or 5.08% in water. 0.045g of that standard is added to the titrator and dissolved in 100ml of the coulomatAG. it spits out a percentage of 5.267%. Is there a way to compare that percent against the standard 5.08%
