1.2 Cups to 0.2839 Liters (I think if I did my math right)
Some of the muscle attached to the skeleton is voluntary and may be used for movement.
Answer:
6.70 g
Explanation:
A common formula for determining the amount of sample remaining in terms of its half-life is
where
t = 458 000 yr
Calculate n
n = 458 000/229 000
n = 2.000
===============
N = 1.675 g Calculate N₀
1.675 = N₀ × 0.2500 Divide by 0.2500 and transpose
N₀ = 1.675/0.2500
N₀ = 6.70 g
The pKa of the dimethylammonium ion, (CH₃)₂NH₂⁺ is 10.7.
<h3>
What do we know about dimethylammonium ion?</h3>
The conjugate acid of dimethylamine, dimethylaminium is an organic cation and a significant species at pH 7.3. It is a secondary aliphatic ammonium ion and an organic cation. It is a dimethylamine conjugate acid.
<h3>What do we understand by pKa?</h3>
In layman's terms, pKa is a measurement of an acid's strength. A strong acid will have a pKa value that is lower than 0. To be more specific, pKa is the Ka value's negative log base ten value (acid dissociation constant). How tightly a proton is retained by a Bronsted acid is how the strength of an acid is measured. The strength of the acid and its capacity to donate protons increase with decreasing pKa values.
