Answer:
2.75 g
Explanation:
The number of moles of KOH is obtained from the equation;
n=CV
C= concentration
V= volume of solution
n= 0.527 × 25.6/1000
n= 0.0135
Reaction equation;
KOH(aq) + KHC8H4O4(aq) --->(KC8H4O4)K(aq) + H2O(l)
1 mole of KHP reacts with 1 mole of KOH
Hence; 0.0135 moles of KHP reacts with 0.0135 moles of KOH
From;
Number of moles = reacting mass/molar mass
Reacting mass = 0.0135 × 204
= 2.75 g of KHP

The answer is the second one 2.3 X 10-3 dm3
Answer: 50% will have short hair
Explanation: The allele for a heterozygous dominant short hair is ( Ss ) and the allele for the homozygous long hair which is the recessive trait is ( ss ).
If we cross these alleles the results will be.
s s
S Ss Ss
s ss ss
The results will have 50% Heterozygous dominant short hair and 50% Homozygous recessive long hair.
