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!
Answer:
PH value greater than 7=baking soda
PH value less than 7=vinegar
PH value equal to 7=pure water
hope it helps.
The answer to this question would be: <span>cs

Electron affinity is determined by the amount of energy released/spent for the atom to add an electron for neutral atoms in gas state.
Lower periodic table means a bigger radius atom. In this case, the distance between the electron to the nucleus is further too, so the affinity is expected to become lower.
In this question, the K and Cs are located in the first column of the periodic table, but Cs located lower. So, the Cs that located lower in periodic table should have a lower affinity.
It doesn't because pepper does not dissolve
