Answer:
N2H4 is commonly called hydrazine, but it could also be named dinitrogen tetrahydride.
Explanation:
<span>the relationship between concentration gradient and active and passive transport would be a direct variation. Concentration gradient is the driving force of these processes. Any transfer, mass or energy, rate is driving force over its resistance. So, it should be a direct relationship.</span>
<h3><u>Answer;</u></h3>
= 0.6224 M
<h3><u>Explanation</u>;</h3>
Molarity is given by the formula;
Molarity = Number of moles/Volume
But moles = mass/Molar mass
Thus;
Moles = 12.47 g/80.043 g/mol
= 0.1556 Moles
Therefore;
Molarity = 0.1556 moles/0.25
<h3> <u>= 0.6224 M</u></h3>
M=43lb = 19,5kg
If 115mg --------- is for --------- 1kg
so
x ---------- is for --------- 19,5kg
x = 19,5kg * 115mg / 1kg
x = 2242,5 mg
