How many используется только с исчисляемыми существительными, т.е. с теми предметами, которые можно посчитать.
Например: - How many oranges are there?
- There are 6 oranges.
How much используется с неисчислимыми существительными, т.е. с теми предметами/продуктами, которые нельзя посчитать. Сюда относятся: meat (мясо), milk (молоко), juice (сок), money (деньги), bread (хлеб) и т.д.
Например: - How much meat are you going to buy?
- I'm going to buy 5 kilos of meat.
То есть неисчисляемые предметы мы можем посчитать только килограммами (мясо), стаканами (сок), банками (мёд, варенье), булками (хлеб), валютой (деньги) и т.д.
Мы не можем сказать 5 meats или 5 milks!
Мы скажем 5 kilos of meat и 5 packages of milk.
