Answer:
Has a hydroxide concentration of 0.01M
Explanation:
When NaOH dissociates, it gives 1mol Na+ and 1mol OH- this multiplies the concentration value and we get 0.01×1= 0.01M
Answer is: n (number of fluorine atoms) is 6, formula of the compound is XeF₆.
m(F) = 0.8682 g; mass of fluorine.
n(F) = m(F) ÷ M(F).
n(F) = 0.8682 g ÷ 19 g/mol.
n(F) = 0.0457 mol; amount of substance.
m(Xe) = 1.00 g.
n(Xe) = 1.00 g ÷ 131.293 g/mol.
n(Xe) = 0.00761 mol.
n(Xe) : n(F) = 0.00761 mol : 0.0457 mol.
n(Xe) : n(F) = 1 mol : 6 mol.
