Penjelasan dan pembahasan
massa P=6%×1 ton=6/100×1000 kg=60 kg
Mr Ca3(PO4)2=310
massa Ca=3×Ar Ca/Mr Ca3(PO4)2×massa P
massa Ca=3(40)/310×60 kg=23,23 kg

maka
kadar Ca =23,23 kg/1000 kg×100%=2,32%

Answer 2

Verified answer

Jawaban:

2,32%

Penjelasan:

massa p = 6% × 1 ton = 6/100 × 1000 kg = 60 kg

Mr Ca3(PO40)2 = 310

massa Ca = 3 × Ar Ca / Mr Ca3(PO4)2 × massa p

massa Ca = 3 × 40 / 310 × 60 kg = 23,23 kg

kadar Ca = 23,23 kg / 1000 kg × 100% = 2,32%

maaf kalau salah
