Question

Teman teman bantu jawab soal kimia no 4 dongg, nanti aku kasih jawaban terbaiikkkkkk

Answer 1

P. V = n. R. T
V=n
mol NO= 7,5/30=0,25 mol
n1/n2=v1/v2
n1/0,25=1/10
n1=0,025 mol
n=gr/Mr
0,025= 2/Mr
Mr= 2/0,025
Mr=80

Answer 2

N1/V1=n2/V2
(2/Mr)/1=(7,5/30)/10
(2/Mr)=0,25/10
20/Mr=0,25
Mr= 80 gram/mol
