Answer:
It's not atom it is an element Strontium.
<span>The functional group in organic chemistry is the set of atoms attached to the carbon skeleton that often determine the properties of an organic compound.
Following are major functional groups that are present in an organic compound. carboxylic acid, ester, ether, amine, amide, thiol, halide, alkene, alkyne, phenol, alcohol, aldehyde, ketone, etc.</span>
<span>To produce a molar conversion, you need to know the molar mass of each molecule.
I presume you mean there are 192 grams of O2. The molecular weight of oxygen is 16 g/mol. Therefore, O2 is 32 g/mole.
If there are 192 grams of O2, then:
192 grams x (1 mole/32g) = 6 moles of O2.
To react each mole of oxygen, you need 2 moles of hydrogen (H2). You can see this in the equation 2H2 + O2 --> 2 H20.
To react 6 moles of O2, you need 12 moles of H2.
Now that we have the total moles of hydrogen needed, we now use the molar mass of H2 (2 grams/mole)
12 moles H2 x (2 grams/1 mol H2) = 24 grams of H2.</span>
Oxygen is gas. It has 2 O atoms. Atomic mass of 1 O atom is 16 amu. So molecular mass of O2 = 2 x 16 = 32 amu.
Now, mass of 6.023 x 10 ^23 = 32 amu.
Therefore mass of 3.01 x 10^23 = 32 x 3.01 x 10^23 / 6.023 x 10 ^23 = 15.99
= ~16 gm
They help us understand the concept of evolution and they help us understand what our earth was like before and after pangea or the great continental drift
