How many egg whites is 400 grams?

It's impossible to give an exact number of egg whites for 400 grams without knowing the size of the eggs.

Here's why:

* Egg size varies: Eggs come in different sizes (small, medium, large, extra-large, etc.). A large egg will have more egg white than a small egg.

* Egg white weight varies: Even within the same size category, individual eggs can vary slightly in their white-to-yolk ratio.

To figure out how many egg whites you need:

1. Check your recipe: Most recipes will specify the size of eggs they require.

2. Weigh a single egg white: If your recipe doesn't specify egg size, weigh a single egg white from the type of egg you're using.

3. Calculate the number of egg whites: Divide 400 grams by the weight of a single egg white.

For example, if a single large egg white weighs 30 grams, you'll need approximately 13 large egg whites for 400 grams.
