What is the maximum amount in moles of P2O5 that can theoretically be made from 211 g of P 4 and excess oxygen Express your answer to three significant figures and include the appropriate units?
The molar mass of P4 is 123.9 g/mol, and the molar mass of P2O5 is 141.94 g/mol. The stoichiometry of the reaction shows that 1 mol of P4 produces 1 mol of P2O5. Therefore, the maximum amount of P2O5 that can be produced from 211 g of P4 is 211 g / 123.9 g/mol = 1.70 mol of P2O5.
How many molecules are contained in 1.50 moles of O2?
Mole to atom conversions require Avogadro's constant, 6.02 × 1023. Take the number of moles and multiply it by Avogadro's constant to get number of atoms. It is usually expressed in scientific notation. 1.50 mole F × (6.02 × 1023) = 9.03 × 1023 atoms F
The formula for the illegal drug cocaine is C17H21NO4 What is the percentage of hydrogen in the compound?
First and foremost, cocaine is NOT cool. To answer your question.... the "percentage of hydrogen" in this molecule pertains to the mass of hydrogen in comparison to the mass of the entire compound. First you must find the total mass, which is easily done by using your periodic table. The masses of each element in your compound are: C: 12 amu (atomic mass units) H: 1 amu N: 14 amu O: 16 amu These masses are rounded for simplicity. In entry level chemistry classes, these numbers will work fine. Now multiply each of these masses by the number of atoms of each element in your compound. (for carbon, 12*17; hydrogen, 1*21; etc.) Add these four numbers to get your compound's total mass. The percent of this mass that is hydrogen is found by dividing the hydrogen mass total by the compound's mass total. You can do this with any of the other elements in the compound to get their respective percentages. (21/303=%H)
What is the balance equation for C14H30 plus O2?
C14H30 + 211/2O2 -> 14CO2 + 15H2O 2C14H30 + 43O2 -> 28CO2 + 30H2O
How can tou get zincs and proteins on Pokemon Diamond and Pearl about 25?
You can find Zinc as a hidden item in Oreburgh Gate and inside Iron Island. Proteins can be found as a hidden item on Route 211 and inside Mt. Coronet. You can also earn Proteins by winning battles against some trainers in the Underground.
How many moles of carbon are in 211 g of carbon dioxide?
Add the atomic weights of one C atom and two O atoms.That's the number of grams in one mole.Use division to find the number of moles in your 211 g.
How many moles of carbon dioxide are in 211 g of carbon dioxide?
To determine the number of moles in 211 g of carbon dioxide, we need to divide the given mass by the molar mass of carbon dioxide. The molar mass of carbon dioxide (CO2) is approximately 44 g/mol. Divide 211 g by 44 g/mol to find that there are approximately 4.80 moles of carbon dioxide in 211 g.
