<span> Because it is diprotic acid, we can write like R(COOH)2 ( it can be written as H2A also)
</span>R(COOH)2+2NaOH ----> R(COONa)2+2H2O
<span>25.0 ml of a 0.100 m NaOH solution
25.0 ml=0.0250 L solution Of NaOH
</span> 0.100 m NaOH=0.100 mol/L
0.0250 L *0.100 mol/L=0.00250 mol NaOH
0.00250 mol NaOH*1mol R(COOH)2/2 mol NaOH=0.00125 mol acid
0.00125 mol R(COOH)2*118g R(COOH)2/1mol R(COOH)2 = 0.148 g acid
Answer is 0.148 g <span>Succinic acid</span>
The answer to this is c i believe
Answer:
A. Molecules have finite volume.
Explanation:
Gases deviate from the ideal gas law at high pressures because its molecules have a finite volume.
Real gases have a finite volume which enables more interaction between the molecules while ideal gases are assumed not to have a finite volume or occupy space which is why it lacks any form of interaction between its molecules.
This difference is the deviation between the real and ideal gases.

C₁₄H₂₂N₄O₈
Explanation:
To find the molecular weight of the compound C₁₄H₂₂N₄O₈ we simply sum that atomic masses of the given elements in the compound.
The empirical weight is determined by using the simplest ratio of the elements involved in the compound;
Molecular weight of C₁₄H₂₂N₄O₈;
atomic mass of C = 12g/mol
H = 1g/mol
N = 14g/mol
O = 16g/mol
Molecular weight = 14(12) + 22(1) + 4(14) + 8(16)
= 168 + 22 + 56 + 128
= 374u
Empirical weight:
Empirical formula:
C₁₄ H₂₂ N₄ O₈
14 : 22 : 4 : 8
divide by 2:
7 : 11 : 2 : 4
empirical formula C₇H₁₁N₂O₄
empirical weight = = = 187u
The molecular formula is the actual combination of atoms in a compound. so the molecular formula of the compound is C₁₄H₂₂N₄O₈
