4 0

Answer:

0.086

Explanation:

A 5.2 molal aqueous solution of methyl alcohol indicates that 5.2 moles of methyl alcohol are present in 1 kilogram (or 1000 g) of water. Water has a molecular weight of 18 g/mol.

(100g)/18g/mol=55.56 mol

5.2 mol/(5.2mol+55.56 mol)=0.086

zhuklara [117]

Answer:

The correct answer is - 1, 2, and 4 statements.

Explanation:

Beta and gamma turns are common plots or turns in proteins and contain intra-turn hydrogen bonds. This hydrogen bond is present between CO of residue i and NH of residue i+3 that holds the confirmation in beta turns.

Beta turns, assist the protein to get their globularity, as the aim of beta turns is to reverse the direction of the polypeptide. The two main of beta turns are type-I and type-Il. and their minor images are type-I and type-Il.

Thus, the correct answer is - 1, 2, and 4 statements.

V₁ = <span>178 mL                  - initial volume 
</span>T₁ = 0 ⁰C = 273K          - initial temperature
V₂ = <span>211 mL                   - final volume
</span>T₂ =?                              - final temperature

According to Charles's law when pressure is constant the Kelvin temperature and the volume will be directly related:

V₁/T₁=V₂/T₂

178/273=211/T₂

0.65=211/T₂

T₂=324K= 51⁰C
