Answer:
7.13mL
Explanation:
P₁V₁T₁ = P₂V₂T₂
P₁ = 3atm , V₁ = 2.1 mL , T₁ = 273 + 4 =277K
P₂ = 0.95atm , V₂ = ? , T₂ = 273 + 25 =298K
V₂ = P₁V₁T₂ / P₂T₁
V₂ = (3atm)(2.1 mL )(298K) / (0.95atm)(277K)
V₂ = 7.13mL
Waves can be described using a number of different characteristics of a wave. Wavelength and frequency are two such characteristics. The relationship between wavelength and frequency is that the frequency of a wave multiplied by its wavelength gives the speed of the wave

Answer:
Erwin Chargaff.
Explanation:
Rule of Chargaff was that any cell organism from the DNA should maintain a ratio of 1:1, this ratio rule is called base pair rule.
And this ratio is maintain between pyrimidine and purine bases and the amount of cytosine should be equal to guanine and also the amount of thymine should be equal to adenine.
Both type of DNA strands show this pattern and this rule was discovered by a chemist who belong to Austria, named was Erwin Chargaff.
