KHP (aq) + NaOH(aq) ---> KPNa (aq) + H2O(l)

Moles of KHP = 0.600 g KHP * \frac{1 mol KHP}{204.23 g KHP} =0.002938 mol KHP

Moles of NaOH = 0.002938 mol KHP * \frac{1 mol NaOH}{1 mol KHP} = 0.002938 mol NaOH

Molarity of NaOH = 0.002900 mol NaOH * \frac{1}{35.00 mL} *\frac{1000mL}{1 L}  = 0.08394 M NaOH

The si unit for measuring acceleration is?
ehidna [41]

m/s² aka meter per second squared.

acceleration = change in velocity/time  

= distance/time

--

time  

= m/s

--

s

=m/s^2

What volume of 0.08892 M HNO3 is required to react completetly with 0.2352 g of potassium hydrogen phosphate?
galina1969 [7]

Answer:

0.0303 Liters

Explanation:

Given:

Mass of the potassium hydrogen phosphate = 0.2352

Molarity of the HNO₃ Solution = 0.08892 M

Now,

From the reaction it can be observed that 1 mol of potassium hydrogen phosphate reacts with 2 mol of HNO₃

The number of moles of 0.2352 g of potassium hydrogen phosphate

= Mass / Molar mass

also,

Molar mass of potassium hydrogen phosphate

= 2 × (39.09) + 1 + 30.97 + 4 × 16 = 174.15 g / mol

Number of moles = 0.2352 / 174.15 = 0.00135 moles

thus,

The number of moles of HNO₃ required for  0.00135 moles

= 2 ×  0.00135 mol of HNO₃

= 0.0027 mol of HNO₃

Now,

Molarity = Number of Moles / Volume

thus,

for 0.0027 mol of HNO₃, we have

0.08892 = 0.0027 / Volume

or

Volume =  0.0303 Liters
