Soralayotgan savol bor (B) elementining 10B izotopining molyar ulushi 19,6% deb berilgan. Borning yana bitta izotopi 11B dir, ularning massasi esa 11,01 b.
10B izotopining molyar ulushi 19,6% bo'lgani uchun uning miqdori quyidagicha hisoblanadi: 10B molyar massasi = (massasi) x (molyar ulushi) = 10,81 x 0,196 = 2,1196
Ushbu sonning borga oxshash bo'lgan 11B izotopining molyar massasini aniqlash uchun, yiroq miqdorini yuzlab, 100% ga taqqoslab qo'ymiz va 10B molyar massasini aynan necha bo'ladi deb hisoblaymiz: 100 / 19,6 = 5,102 5,102 x 2,1196 = 10,81 - 2,1196 = 8,6904
Shunga ko'ra, 11B izotopining molyar ulushi 8,6904% bo'ladi.
