Answer:

60g/mol

Explanation:

By using nucleon numbers given on the periodic table, the mass of 1 mole of each element is:

C= 12g

H= 1g

O= 16g

Since molar mass is the sum of the masses of each element present in the compound,

Molar Mass (Mr) = 12+3(1)+12+16(2)+1 = 60g/mol

Answer:

Percentage of mass of solute in aqueous phase is 28.57%.

Explanation:

(q)_{aq}- Fraction of solute in aqueous phase.

(q)_{aq}=\frac{V_{aqueous}}{DV_{organic}+V_{aqueous})}

V_{aqueous} = Used volume of aqueous solution

V_{organic} = Used volume of organic solution

D = partition coefficient.

(q)_{aq}=\frac{100ml}{(2.5\times100)+100\,ml}=0.2857

Mass of solute in aqueous phase = 0.2857\times 5g=1.428g

Mass\,percentage = \frac{1.428}{5.0}\times 100=28.57

Therefore, Percentage of mass of solute in aqueous phase is 28.57%.

Write einstein's equation that explains the energy from nuclear reactions. _________ use the caret symbol (^) to show an exponen
Katen [24]
I would say it should be Einstein's famous equation of e=mc^2 which means energy =mass x the speed of light squared. With this equation Einstein showed that energy comes from a mass travelling at the speed of light squared which is a fundamental equation to explain physical phenomena.
