How many kilo joules are in a glass of lemonade?

I can't give you an exact number of kilojoules in a glass of lemonade without knowing the specific recipe and size of the glass.

Here's why:

* Ingredients: The amount of sugar, lemon juice, and water will all impact the calorie (and therefore kilojoule) content.

* Glass size: A small glass will contain fewer kilojoules than a large glass.

To get an estimate:

1. Check the nutritional label: If you're using a pre-made lemonade mix, the label will usually list the calories per serving.

2. Use a calorie calculator: Online calculators can help you estimate the calories (and convert to kilojoules) based on your specific ingredients and portion sizes.

Remember:

* 1 calorie = 4.184 joules

* 1 kilojoule (kJ) = 1000 joules

Let me know if you have the ingredients and glass size, and I can help you calculate the approximate kilojoules!
