Ответ:

Чтобы определить массу оксида фосфора (P2O5), сначала нужно узнать соотношение массы кислорода к массе оксида фосфора в уравнении реакции. В данном случае, массовое соотношение равно 1:2.

Таким образом, если у вас есть 160 г кислорода, масса соответствующего оксида фосфора будет 160 г * 2 = 320 г.

Объяснение:

сначала надо уравнять реакцию так как:

4P+5O2—>2P2O5

m1/M1=m2/M2 ;

160г/(5×32)г/моль=Хг/(4×31+10×16)г/моль

от туда Х=284г

The sundial was one of the first timekeeping devices created, and dates back to 1). Roman and Greek societies.
