1.5 = 1500g/Volume


Rearrange the equation:


Volume = 1500/1.5 = 1000


So your answer is 3. 1000 cm3

ara h 6 complements ara h 2 as an important marker for ige reactivity to peanut audrey e. koid,† martin d. chapman,†
frez [133]

Purified Ara h 6 will be helpful for research into the immunological mechanisms underlying peanut allergy, including molecular and cellular studies, diagnostic IgE antibody testing, and clinical trials.

1.4% of children and 0.6% of adults in the United States suffer from the food allergy peanut. Approximately 1.8% of youngsters in the UK are allergic to peanuts. Food allergies to milk, eggs, and wheat are often outgrown by children, while allergies to peanuts are more persistent and frequently last into adulthood. As little as 0.4 g of peanut is required to cause milder allergic reactions like rashes, angioedema, and gastrointestinal problems. However, peanut is also one of the leading causes of severe, sometimes fatal anaphylactic reactions.

nevsk [136]

Answer:

Phenols do not exhibit the same pka values as other alcohols;

They are generally more acidic.

Using the knowledge that hydrogen acidity is directly related to the stability of the anion formed, explain why phenol is more acidic than cyclohexane.

Explanation:

According to Bromsted=Lowry acid-base theory,

an acid is a substance that can release H^{+} ions when dissolved in water.

So, acid is a proton donor.

If the conjugate base of an acid is more stable then, that acid is a strong acid.

In the case of phenol,

the phenoxide ion formed is stabilized by resonance.

C_6H_5OH -> C_6H_5O^- +H^+

The resonance in phenoxide ion is shown below:

Whereas in the case of cyclohexanol resonance is not possible.

So, cyclohexanol is a weak acid compared to phenol.
