Answer:
2.107×10²⁴
Explanation:
no of moles=no of particles/Avogadro's number
3.5=X/6.02×10²³
by cross multiplication
3.5×6.02×10²³
=2.107 ×10²⁴
hey there!
atomic mass cobalt = 58.9332 amu
therefore:
1 mol Co ------------ 58.9332 g
moles ------------ 50 g
moles = 50 x 1 / 58.9332
moles = 50 / 58.9332
= 0.8484 moles of Co
Hope this helps!
