PV=mRT/M; V = mRT/PM; R = R = 8,31431 Дж/моль. К m = 12 г = 0,012 кг; P = 30 атм = 30 * 10^5 Па; T = 0C = 273K; M=28*10^ (-3) кг/м V = 0,012 * 8,31 * 273/30 * 10^5 * 28*10^ (-3) = 27,22/84000 = 0,00032 м3 = 0,32 дм3;

решите каждое уравнение двумя способами:

а) (х+98) + 14 = 169
х+98=... - ...
х+98 = ...
х = ...

(и еще вторым способом)

(х+98)+14=169
х+ ...+ ... = 169
х+ ... = 169

б) (35+у) - 15 = 3135+у = 31 ... 15
35+у= ...
у = ...

(и вторым способом)
(35+у) - 15 = 31
(35 - ...) + у = 31
... + у = 31
