Answer 1

Ответ:

n находится по формуле объем умножить на vm=22.4 л

а масса молекулярную массу умножить на n

Answer 2

It seems like you're providing an equation or expression: "DanоV(N2) = 7,81 л.m(N2) - ?". However, it's not entirely clear what you're asking or what the context of this expression is.

It appears to involve some kind of measurement or calculation involving nitrogen gas (N2), possibly related to volume (V) and mass (m). If you could provide more context or details about what you're looking for, I'd be happy to help you understand or interpret this expression.
