The volume of the unknown solution obtained from the given standard curve is 2.57%
The linear equation produced by the standard curve is :

- y = absorbance ;
- x = concentration in percent (v/v)
Unknown Solution with absorbance value of 0.35 ;
Input the value of y into the equation.

Collect like terms


Divide both sides by 0.136



Hence, percentage by volume of the unknown solution will be 2.57%

Answer:
the genotype is responsible for a particular trait or all of the traits
Explanation:
Yes because we use the sun light as a way to grow crops for one so no one would be getting any food and plant life would never grow and would die so we wouldn't be getting Air as well because trees and plants make oxygen for us
Tycho Brahe play in determining planetary orbits his model allowed the path of the planet Mars to cross through the path of the sun. Thus, option B is correct.
<h3>What was Tycho Brahe's greatest contribution to astronomy?</h3>
He rater utilize the telescope to create vast astronomical remarks. He resolved that the planets circle the Sun in oval orbits.
He offered some easy laws that rule the motion of the planets and other entity.
Thus, option B is correct.
