Jawaban:
Massa = 30 gram
Penjelasan:
pertama, kita cari Mr CO(NH₂)₂
Mr CO(NH₂)₂ = Ar C + Ar O + (2 x Ar N) + (4 x Ar H)
karena disitu sudah diketahui, maka tinggal masukkin saja angkanya.
= 12 + 16 + (2 x 14) + (4 x 1)
= 28 + 28 + 4
= 60 gr/mol
menghitung massa
[tex]mol = \frac{massa}{Mr}[/tex]
[tex]massa = mol \times Mr[/tex]
[tex]massa = 0,5 \: mol \times 60 \: g/mol[/tex]
[tex]massa = 30 \: gram[/tex]
