soal tentang stoikiometri/mol kimia kls 10 sma. tolong bantu ya, jgn jawab asal-asalan nanti kena report​

Jawaban:

32 gram

sepertinya di soal salah ketik volume, harusnya 24,6 L

jika volumenya 24,6 mL nanti jawabannya 0,032 gram

Penjelasan:

gunakan rumus gas ideal PV = nRT

dimana

P : tekanan (atm)

V : volume (L)

n : mol

R : tetapan gas ideal 0,082 L.atm/mol.K

T : suhu (K)

Diketahui

P = 1 atm

V = 24,6 L

T = 27°C = 300K

Mr O2 = 32

Ditanya : massa O2 = ?

Jawab

[tex]PV = nRT[/tex]

[tex]PV = \frac{gram}{Mr} RT[/tex]

[tex]gram = \frac{PVMr}{RT} = \frac{1 \times 24.6 \times 32}{0.082 \times 300} = 32 \: gram[/tex]
