Elemental analysis of a compound containing carbon, hydrogen, nitrogen, and oxygen gave the following mass percentages for each element: C: 42.36% H: 3.555% N: 16.47% O: 37.62% The <em>molar mass</em> of the compound is Molecular formula = C6H14N2O2 Consider the total mass of the compound =100g Then mass of carbon = 49.30 g Mass of hydrogen = 9.653 g Mass of nitrogen = 19.16 g Mass of oxygen = 21.89 g Molar mass of carbon = 12.0 g/mol
<h3>What is
molar mass ?</h3>
In chemistry, the molar mass of a chemical compound is determined by dividing its mass by the molecular weight of the component that makes up the sample. The molar mass of a substance is a bulk attribute rather than a molecular one. The compound's molar mass is an average over numerous samples, which frequently have different masses because of isotopes. A terrestrial average and a function of the relative abundance of the isotopes of the constituent atoms on Earth, the molar mass is most frequently calculated using the standard atomic weights. For converting between a substance's mass and amount in bulk amounts, the molar mass is the proper unit.

Answer:
Potassium Dichromate is an orange to red colored, crystalline, inorganic compound that emits toxic chromium fumes upon heating. Potassium dichromate is highly corrosive and is a strong oxidizing agent. This substance is used in wood preservatives, in the manufacture of pigments and in photomechanical processes, but is mainly replaced by sodium dichromate. Potassium dichromate primarily affects the respiratory tract causing ulcerations, shortness of breath, bronchitis, pneumonia and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity. (NCI05)

Cause wave's get larger and larger and it will repeat over and over
(please mark me brainly est)
First, since l = n-1,
5,4,-5,1/2 and 2,1,0,1/2 are the only answer choices left.
Next, since ml = -l to l,
2,1,0,1/2
is the answer because in 5,4,-5,1/2, the ml value of -5 is not in the range of -4 to 4, as notes by the value 4 for l.
