Molar mass
Ca₃(PO₄)₂ = 310 g/mol
1 mole -------------------> 310 g
2.3x10⁻⁴ mole ---------> ?
m = 2.3x10⁻⁴ * 310 / 1
m = 0.0713 g
hope this helps!
Answer:
–1
Explanation:
The electronic configuration of the neutral atom is given below:
2 8 7
From the electronic configuration of the neutral atom, we can see that the atom has 7 electrons in it's outermost shell. This implies that the element needs 1 more electron to complete it's octet configuration.
Therefore the charge on the ion of the element will be –1 indicating that the atom has received 1 electron to complete it's octet configuration.
