How many grams per sachet? Can it be dissolved and used to measure multiple times? If mixed with water at once, then add กันเสีย save it y (If possible, use กันเสีย which doesn't affect ph)

Hello, I have to mix them all at once. Each sachet will be notified that it must be mixed with 250ml of water (or equal to 250g of water). Turn it on and use it all. used and discarded can not be used again
