b. 2 mol gas nitrogen dioksida

c. 0,25 mol besi

d. 0,5 mol natrium klorida $undefined$

Pembahasan Soal:

a. 0,1 mol tembaga

$begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell Jumlah space partikel space end cell equals cell space n space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 0 comma 1 space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 6 comma 02 cross times 10 to the power of 22 end cell end table end style$

b. 2 mol gas nitrogen dioksida

$begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell Jumlah space partikel space end cell equals cell space n space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 2 space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 12 comma 04 cross times 10 to the power of 23 end cell end table end style$

c. 0,25 mol besi

$begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell Jumlah space partikel space end cell equals cell space n space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 0 comma 25 space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 1 comma 505 cross times 10 to the power of 23 end cell end table end style$

d. 0,5 mol natrium klorida

$begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell Jumlah space partikel space end cell equals cell space n space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 0 comma 5 space cross times space 6 comma 02 cross times 10 to the power of 23 end cell row blank equals cell space 3 comma 01 cross times 10 to the power of 23 end cell end table end style$

Jadi, jawaban yang benar adalah jumlah partikel = $begin mathsize 14px style 6 comma 02 cross times 10 to the power of 22 end style$ ; $begin mathsize 14px style 12 comma 04 cross times 10 to the power of 23 end style$ ; $begin mathsize 14px style 1 comma 505 cross times 10 to the power of 23 end style$ ; $begin mathsize 14px style 3 comma 01 cross times 10 to the power of 23 end style$ .
