I think the answer is solvent but i'm not very sure.
Answer:
it depends on the subject but i can see what i can do
Explanation:
Answer:
0.05 M
Explanation:
Mass of benzoic acid= 0.158g
Volume of benzoic acid= 100 mL
Volume of sodium hydroxide = 27.84mL
Molar mass of benzoic acid= 122g/mol
Number of moles of benzoic acid= 0.158g/122g/mol= 1.3 × 10^-3 moles
C= no of moles/volume
C= 1.3 × 10^-3 moles × 1000/100
C= 0.013M
So;
Volume of acid VA = 100mL
Concentration of acid CA= 0.013M
Volume of Base VB = 27.84mL
Concentration of Base CB= ???
Number of moles of acid NA =1
Number of moles of Base NB= 1
From;
CAVA/CBVB= NA/NB
CAVANB= CBVBNA
CB= CAVANB/VBNA
CB= 0.013 × 100 × 1/27.84 × 1
CB= 0.05 M
