Answer:
2.61
Explanation:
pH+pOH=14, so sub in 11.39 for pOH, then subtract it over to get pH=2.61

Answer:
is the molecular formula of the compound.
Explanation:
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :
We are given:
Mass of molecular formula = 200 g/mol
Mass of empirical formula of
:
2 × 12 g/mol + 1 × 1 g/mol + 4 × 19 g/mol = 101 g/mol
Putting values in above equation, we get:
Multiplying this valency by the subscript of every element of empirical formula, we get:

is the molecular formula of the compound.
