Question

При сжигании в кислоте 62 грамма фосфора было получено 130грамм оксида фосфора (V) от теоретически возможно. Вычислите массовую долю выхода оксида фосфора(V)

Answer 1

Такое невозможно! В данной реакции с кислотой оксид не выделяется! Проверь, может неправильно написал...

Answer 2

Calculation of the Mass Fraction of Phosphorus(V) Oxide

To calculate the mass fraction of Phosphorus(V) oxide (P2O5) produced when 62 grams of phosphorus is burned in acid, we need to compare the mass of the P2O5 produced to the initial mass of phosphorus.

Given: - Mass of phosphorus burned = 62 grams - Mass of Phosphorus(V) oxide produced = 130 grams

To calculate the mass fraction, we use the formula:

Mass Fraction = (Mass of P2O5 produced / Mass of phosphorus burned) * 100

Substituting the given values into the formula:

Mass Fraction = (130 grams / 62 grams) * 100

Calculating the mass fraction:

Mass Fraction = 209.68%

However, it is important to note that the calculated mass fraction of 209.68% seems to be incorrect, as it exceeds 100%. This suggests that there may be an error in the given information or calculation. Please double-check the values provided and ensure they are accurate.
