Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions.
Norma-Jean [14]

2 KHP(aq) + Ba(OH)_{2}(aq) ---> KP_{2}Ba (aq) + 2 H_{2}O (l)\

Moles of Ba(OH)_{2}=0.483 \frac{mol}{L} * 28.5 mL *\frac{1 L}{1000mL}  = 0.0138 mol Ba(OH)_{2}

Mass of KHP = 0.0138 mol Ba(OH)_{2} * \frac{2 mol KHP}{1 mol Ba(OH)_{2}}  * \frac{204.22 g KHP}{1mol KHP}

= 5.64 g KHP

Which of the following covalent bonds is the most polar?
Bezzdna [24]

Answer:

D.) H-O

Explanation:

Polarity is determined based on the difference in electronegativity of the atoms. The greater the difference, the more polar the bond. The general trend is that the atoms in the top-right corner of the periodic table are the most electronegative.

A.) is incorrect because H-H has no electronegativity difference, making it nonpolar.

B.) and C.) are incorrect because their electronegativity differences are not the greatest.

D.) is correct because the electronegativity difference between the H and O is the greatest.
