Answer: The solution to the problem expressed to he correct number of significant figures is 1.69
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule applied for multiplication and division is :
The least precise number determines the number of significant figures in the answer.
As 12.0 has 3 significant digits and 7.11 also has 3 significant digits, the answer would also contain 3 significant digits.
For 
Thus the solution to the problem expressed to he correct number of significant figures is 1.69
Answer: Homogeneous mixture
Explanation:
Homogeneous mixtures are those mixtures in which the dispersed phase is uniformly distributed throughout the dispersion medium. The dispersed phase has uniform composition throughout the dispersion medium and thus there is no physical boundary between the dispersed phase and the dispersion medium. Example: salt in water
Heterogeneous mixtures are those mixtures in which the dispersed phase is not uniformly distributed throughout the dispersion medium. The dispersed phase does not has uniform composition throughout the dispersion medium and thus there is a distinct physical boundary between the dispersed phase and the dispersion medium. Example: Sand in water
V(NaOH)*M(NaOH)=V(HCOOH)M(HCOOH)
35.43ml*0.1150m=20.00ml*M(HCOOH)
M(HCOOH)=0.2037m
