How to calibrate dosing pupms by saltwater weight?

My dosing pump calibration by volume hasn't worked well and I want to calibrate by weight. What is the weight/volume calculation for 35ppt water?

You are weighing the water to get volume more accurately? That's a fine plan.

Just assuming 1 mL = 1 g will only be off (too low of volume) by 2.5%.
