Question

Hitunglah Mr yang ada pada gambar berikut.

Jika : Ar C → 12
Ar H → 1
Ar O → 16​

Answer 1

Jawaban:

Mr = 58 g/mol = 58 sma

Penjelasan:

Mr CH3COCH3 = Ar C x 3 + Ar O x 1 + Ar H x 6

Mr CH3COCH3 = 12 x 3 + 16 + 6

Mr CH3COCH3 = 36 + 16 + 6 = 58 g/mol

.

Mr CH3 COCH3 = 58

.

» Penyelesaian

Diketahui:

Ar C = 12

Ar H = 1

Ar O = 16

.

Ditanya:

Mr CH3 COCH3

.

Jawab:

Mr CH3 COCH3 = (ArC×3)+(ArH×6)+(ArO)

= (12×3)+6+16

= 36+22

= 58
