In this question, you are given the average cofactor mass per cell (77.91pg) and the total cells count(10^5 cells). You are asked how much cofactor that will be found from those cells(microgram= 10^6 picogram). Then the calculation would be:
Cofactor mass= cofactor per cell * cell count= 77.91pg/cell * 10^5 cells= 7.791 x 10^6pg
Then convert the picogram(pg) into microgram: 7.791x 10^6pg/ (10^6pg/microgram)= 7.791 microgram
Answer:
B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]
Explanation:
For the reaction A + B → C
The formula for rate of reaction is:
Δ[C]/Δt = k [A] [B]
As you have [A], [B] and Δ[C]/Δt information you can multiply [A] times [B] and take this value as X and Δ[C]/Δt as Y. The slope of this lineal regression will be k.
Thus, you must obtain:
y = 3,60x10⁻² X
Thus, rate of reaction is:
B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]
I hope it helps!
Solution:
According to the Avogadro's number:
6.022 *10^23 drops per 0.050 g/ drop = 3.011 *10^22 grams per mole of drops
3.011 *10^22 grams per 1 kg / 1000 grams = 3.011 *10^19 kilograms / mole of drops
thus the answers are:
3.0 *10^22 grams per mole of drops
3.0 *10^19 kilograms per mole of drops
And,
In the calculation of how many moles of raindrops in the Pacific Ocean is:
7.08X10^20kg per 3.0 *10^19 kilograms per mole of drops = 23.5 moles of drops
This is the required solution.
