If you're diabetic (type 2) on insulin and have a hypo how much glucose or dextrose is required in order to increase blood sugar levels by 1 mmol?

Hypoglycemia: There is no precise answer. It depends on how much Insulin you took, what you ate, how fast the glucose falls, etc. If you have a severe reaction, you need to eat, but sometimes people with diabetes take in too much glucose, causing wide swings in blood glucose when in fact only a little glucose is needed. Glucose tablets give you a measured amount of sugar which you can regulate.
