John Dalton and Antoine Lavoisier were alchemists who tried to convert diamonds to gold.
larisa86 [58]
This is false. They were both chemists and they made many discoveries such as realizing that charcoal and diamond are different forms of the same element and proposing an atomic theory, but they never tried to turn diamonds to gold.

Answer:

The molecular formula of estradiol is: C_{18}H_{24}O_2.

Explanation:

Molar mass of of estradiol = M= 272.37 g/mol

Let the molecular formula of estradiol be C_xH_yO_z

Percentage of an element in a compound:

\frac{\text{Number of atoms of element}\times \text{Atomic mass of element}}{\text{molecular mass of element}}\times 100

Percentage of carbon in estradiol  :

\frac{x\times 12 g/mol}{272.37 g/mol}\times 100=79.37\%

x = 18.0

Percentage of hydrogen in estradiol  :

\frac{y\times 1g/mol}{272.37 g/mol}\times 100=8.88\%

y = 24.2 ≈ 24

Percentage of oxygen in estradiol  :

\frac{z\times 16 g/mol}{272.37 g/mol}\times 100=11.75\%

z = 2

The molecular formula of estradiol is: C_xH_yO_z:C_{18}H_{24}O_2

Why do living things need carbon
soldier1979 [14.2K]
Animals use oxygen to convert this food into energy they can use, and to maintain a steady supply of carbon atoms that are necessary for building any animal cells. Respiration also returns carbon dioxide back to the atmosphere as a waste product, where plants can reabsorb it in the process of photosynthesis. hope I helped.
