What color is your blood. Red, right? Well, actually, yes. So why does it look blue when you see it through your skin? And is everyone's blood always the same color red (spoiler: no)? Do all animals have red blood ('nother spoiler: no!)? And why is red blood red anyway?
One large egg weighs approximately 2 ounces. Each egg is classified  into medium, large, extra large, and jumbo based on their actual  weight.
One large egg weighs 50 grams, which is about 2 ounces. By volume, one large egg is 1/4 cup, which is also 2 ounces. IIRC, the amount of yolk and the amount of white is about half and half, so it should be one ounce for each.
