Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

Sir, With all due respect. When you come up with Urea Nitrogen level 14mg/dL, The nitrogen level would be 14 AMU for both nitrogen in single urea molecule as test doesn't detect the Nitrogen of only one bond, it measures on both bonds attached to "C" . Hence, 1 molecule of urea = 14AMU Urea Nitrogen 1 mol Urea= 14 gm urea Nitrogen 1mMol Urea= 14 mg urea Nitrogen If I am wrong, plz explain if possible.

I’m so frustrated…. On a water fast and picked up some electrolytes. The package says it contains 112 mosmol/l of dextrose. Trying to figure out how many grams of sugar this is and if it will stop the autophagy phase.

How did you come up with the weight of Carbon (12) and Oxygen (16)?
@michiel350
@michiel350 5 жыл бұрын
That is the molecular mass, you can find them in the periodic table. It's useful to know some the weight of the common atoms such as H, O, C by heart.

When you converted grams to milligrams, did you forget to divide? You just rewrote 180g as 180mg, not an accurate conversion.

+Ashlyn Engleman The conversion is correct, as the proctor also converts moles to millimoles, keeping the divisors constant
