The molar concentration of the original HF solution : 0.342 M
Further explanation
Given
31.2 ml of 0.200 M NaOH
18.2 ml of HF
Required
The molar concentration of HF
Solution
Titration formula
M₁V₁n₁=M₂V₂n₂
n=acid/base valence (amount of H⁺/OH⁻, for NaOH and HF n =1)
Titrant = NaOH(1)
Titrate = HF(2)
Input the value :
The Rivergate because you are basing the distance off of there
Answer:
It has 3 significant figures
Explanation:
Numbers after decimal are significant figures and zero before decimal is not a significant number.
Hence significant figures are 1,1&5
The vascular cambium also known as the main cambium the wood cambium plural cambium is a plant tissue located between the xylem and the phloem
A supersaturated solution holds
less solute than it normally can is false. It actually contains more solute
that it normally can. Having less solute than it normally can is an unsaturated
solution. And when it has the exact amount of solute, it is a saturated solution.
