Answer:
7,01 g of indole-3-acetic acid
Explanation:
The milimolar concentration (mM) is defined as the ratio of milimoles per Liter of solution. 400mM means 400mmoles / L that is the same of <em>0,4mol / L</em>
100mL are <em>0,1L</em>. Using these values:
0,1L × (0,4mol / L ) = 0,04moles of indole-3-acetic acid.
As the MW of the molecule is 175,2 g/mol:
0,04mol × (175,2g / mol) = <em>7,01 g of indole-3-acetic acid</em>
<em></em>
Thus, <em>you need 7,01 g of indole-3-acetic acid to generate your solution</em>.
I hope it helps!
Answer:
The correct answer is option c, that is, H2O.
Explanation:
The two broad classes of molecules are the polar and nonpolar molecules. Polarity illustrates the dispersion of electrical charge surrounding a molecule. The charge is unevenly distributed in a polar molecule, while it is distributed evenly in a nonpolar molecule. It can be said that a polar molecule possesses the regions of partial charge.
A polar molecule like water possesses a dipole, that is, a part of the molecule exhibit a partial negative charge, and the part of the molecule possesses a partial positive charge. Generally, a polar molecule comprises polar or ionic covalent bonds. The polar molecules are generally soluble in polar solvents and are hydrophilic. They have higher melting points because of the strong intermolecular forces between them in the form of hydrogen bonding.
In the given options, H2O is a polar molecule as the hydrogen atoms electrons get fascinated towards the oxygen atom's electrons, which forms a positive charge on the atoms of hydrogen, and a negative charge on the oxygen atom.
