PH= log[H3O+]
10.25=log [H3O+]
[H3O+] = 10^10.25
[H3O+]= 1.778 ×10^10

<span>pH + pOH = 14 10.25 + pOH = 14 pOH = 14 - 10.25 = 3.75 Now, knowing the pOH we can find the OH^- since pOH is -log [OH-] [OH-] = 10^-3.75 = 1.78x10^-4 M</span>

Does anyone know how to find mass of NaN3?

Alexus [3.1K]

The molar mass (atomic weight ) of sodium is 23.0 grams/mole and the molar mass of sodium azide, NaN3 , is the mass of sodium, 23.0 gram/mole added to the molar mass of three atoms of nitrogen (14.0 x 3 = 42 gram/mole) which equals 65.0 grams/mole. The percentage of sodium is 23.0 /65.0 x 100 % = 35 %

IRISSAK [1]

Answer: The molecular mass of this compound is 131 g/mol

Explanation:

Depression in freezing point:

$\Delta T_f=i\times k_f\times \frac{w_2\times 1000}{M_2\times w_1}$
