Well, it depends on what you tested and how you tested it, but seeing as you probably used the 'dry the pieces and find the weight difference before and after' method, your control would be the weight of the orange BEFORE drying it.
An orange is made of about 70% of water
Your variable in the 'How Much Water is in an Orange' experiment will be- Independent variable: The amount of water in the orange. Why? Because this is what you physically changed. Dependent variable: The weight of the dried orange. Why? Because this is what happened after you removed the water.
80 to 90%
The method probably involves weighing the orange before it is dried, then again after it is dried. (Mass normal orange)-(mass dried orange)= (mass water in orange)
about 80% of an orange is made up of water.
there is 87% who didnt know that
Not as much as water. Water has a ton of sugar in it.
3 parts of water
If you think about it, the juice and pulp from 1 orange would pretty much be 1 orange. Sort of asking how much wood would replace a tree.
Answer it yourself!
There are 6.9 grams of sugar per 100ml of Fanta Orange.
water is 0% orange, but the % of water in an orange is 52.7652%
