Potasyum-40 küçük atom numaralı doğal radyoaktif birkaç element izotopundan biridir ve doğada K izotopları içerisindeki bolluk y
enot [183]

Answer:

6.707 × 10¹⁷

Explanation:

From the information given:

40 ^ K kütlesi = sütteki K kütlesi × 40 ^ K / 100 kütle yüzdesi

nerede;

sütteki K kütlesi = 1.65 mg of K/mL × 225 mL = 371.25  mg of K

∴

40 ^ K kütlesi = 371.25  × 0.012/100

40 ^ K kütlesi = 0,04455 mg = 4.455 × 10⁻⁵ grams

40 ^ K mol sayısı = 40 ^ K kütlesi / molar kütle

= 4.455 × 10⁻⁵/40

= 1.11375 × 10⁻⁶

Son olarak, 40 ^ K = mol × Avogadro sayısı atomları

= 1.11375 × 10⁻⁶  × 6.022 × 10^23

= 6.707 × 10¹⁷
