How many moles of phosphorus are in a 73.5 mol solution of P4O10?
There are 73.5 moles of P4O10 per kg of solution. Each P4O10 molecule weighs approximately 283.88 g. P makes up 123.88 or about 77.43% of this. 73.5 moles of P4O10 weighs about 20865.18 g. 77.43% of 20865.18g is 16155.91 g. Multiply this by the inverse of the molar mass of P (30.97g /mol) and your answer should be approximately 521.66 moles of P.
What is the mass number of phosphorus?
Phosphorus is a non metal. atomic number of it is 15.
How many moles of phosphorus?
The number of moles of phosphorus depends on the given quantity or mass of phosphorus. To calculate the number of moles, you need to know the molar mass of phosphorus (about 30.97 g/mol) and the mass of the sample. You can then use the formula moles = mass/molar mass to find the number of moles.
What is Phosphorus's mass number?
i dont know if u what u meant but here's this Atomic Number: 15 Atomic Mass: 30.97376
What is the percent composition by mass of phosphorous in ammonium phosphate?
Ammonium phosphate ((NH4)3PO4) contains one phosphorus atom in the formula. To calculate the percent composition by mass of phosphorus, you need to find the molar mass of phosphorus and the molar mass of the entire compound. Then, divide the molar mass of phosphorus by the molar mass of the compound and multiply by 100 to get the percentage.
What number of moles of O2 is needed to produce 142 grams of P4O10 from P?
We first calculate the molar mass of P4O10, which is 284 g/mol. Then we convert the given mass of P4O10 (142 g) to moles using its molar mass. There is a 1:4 molar ratio between P4O10 and O2 in the reaction, so we multiply the moles of P4O10 by 4 to find the moles of O2 needed.
How many moles of phosphorus are in a 73.5 mol solution of P4O10?
There are 73.5 moles of P4O10 per kg of solution. Each P4O10 molecule weighs approximately 283.88 g. P makes up 123.88 or about 77.43% of this. 73.5 moles of P4O10 weighs about 20865.18 g. 77.43% of 20865.18g is 16155.91 g. Multiply this by the inverse of the molar mass of P (30.97g /mol) and your answer should be approximately 521.66 moles of P.
How many molecules of tetraphosphorus decoxide contain 29.6g of phosphorus atoms?
Since tetraphosphorus decaoxide has the formula P4O10, it contains 4 phosphorus atoms per molecule. The molar mass of P4O10 is 284.09 g/mol. To find the number of moles of phosphorus atoms in 29.6g, divide the mass by the molar mass, then multiply by Avogadro's number (6.022 x 10^23) to get the number of molecules.
There are 5400 moles of P4O10 what is the mass?
The molar mass of P4O10 is 284.9 g/mol. Therefore, the mass of 5400 moles of P4O10 would be 1,537,848 g or 1537.8 kg.
When 31 grams of phosphorous reacts with oxygen 71 grams of an oxide phosphorus is the product. What mass of oxygen is needed to produce 13 grams of this product?
To find the mass of oxygen needed to produce 13 grams of the oxide, we first find the molar ratio between P and O in the product. Then, use this ratio to calculate the mass of oxygen needed. Since 71g of the oxide contains 31g of phosphorus, we can calculate the mass of oxygen needed for 13g of the oxide by setting up a proportion.
What element has a molar mass of 30.974 g?
The element with a molar mass of 30.974 g is phosphorus.
What is the mass number of phosphorus?
Phosphorus is a non metal. atomic number of it is 15.
What is the average atomic mass of phosphorus?
why would I know this sit would not give me the answer :[
What is the percentage by mass of phosphorus in Na3PO4?
Phosphorus has a molar mass of 30.97 g/mol, while the molar mass of Na3PO4 is 163.94 g/mol. To find the percentage by mass of phosphorus in Na3PO4, divide the molar mass of phosphorus by the molar mass of Na3PO4, and multiply by 100. This gives a percentage by mass of approximately 18.9% phosphorus in Na3PO4.
How many moles of phosphorus?
The number of moles of phosphorus depends on the given quantity or mass of phosphorus. To calculate the number of moles, you need to know the molar mass of phosphorus (about 30.97 g/mol) and the mass of the sample. You can then use the formula moles = mass/molar mass to find the number of moles.
Why is 40 the mass number of phosphorus?
Phosphorus is a non metal element. Mass number of it is 31.
What is the atomic mass of phosohorous?
The atomic mass of phosphorus is approximately 31. Although it can vary slightly depending on the isotope of phosphorus, the most common isotope, phosphorus-31, accounts for the majority of naturally occurring phosphorus.
