Answer is s orbital. Hopes this helps
Hey did you ever find the answers to this?
Answer:
pH = 2.5
Explanation:
Given data:
Concentration of HBr = 0.003 M
pH of solution = ?
Solution:
Formula:
pH = -log[H⁺]
by putting values,
pH = -log [ 0.003]
pH = 2.5
(125 mg Na) x (1 g/1000mg) x (1 mol of Na/22.99 g) = 5.43 E -3 mols of Na
5.43 E -3 mols x 6.022 E 23 = 3.27 E 21 Na atoms
I think its most likely to be A,
