<u>Solution</u> : Emperical Formula = 
Emperical Formula - A formula that gives the simplest whole number ratio of atom in a compound.
In the question percentages are given then assume that the total mass is 100grams so that the mass of each element is equal to the percentage given.
Given : 80.0g Carbon
20.0g Hydrogen
First convert the given masses into moles.
Value of each mole divided by the smallest number of moles and then round off.
Moles ratio of the element are
This is the mole ratio of the elements and is repersented by the subscript in the emperical formula.
Emperical Formula =
Answer:
Lactic acidosis occurs when there is greater than 1.60 g in 4445 mL of blood
Explanation:
A normal blood lactic acid level is 0.5-1 mmol/L.
Mild to moderately elevated level of blood lactic acid known as hyperlactatemia occur when the range is between 2-4 mmol/L without metabolic acidosis.
Lactic acidosis occurs with blood lactic acid levels of > 4 mmol/L
Molar mass Lactic acid, C₃H₆O₃ = 90 g/mol
Mass 4 mmol lactic acid = 0.004 mol * 90 g/mol = 0.36 g
Mass of lactic acid in 1 litre or 1000 mL of blood = 0.36 g
Mass of lactic acid in 4445 mL of blood = 0.36 g * (4445/1000)
<em>Mass of lactic acid in 4445 mL of blood = 1.60 g</em>
If you want to know who that person is, then the correct answer is Niels Bohr.
Niels Bohr described atoms as having a positive nucleus with electrons that have different energies at different distances from the nucleus.
He was a famous Danish physicist whom we can thank for groundbreaking discoveries regarding quantum physics.
