No' of molecules divide by avogadro number , 6×6.023×10^23 so (2.2×10^22)÷(6.023×10^23)
= 0.03653 moles
moles × Molar mass = mass
n×Mr=m
0.03653×40 = 1.46 grams
The answears are in the attached photo.
The purport of mitosis is cell regeneration, magnification, and asexual reproduction,while the purport of meiosis is the engenderment of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are conventionally partitioned into two incipient daughter cells.
Answer:
<h3>The answer is 0.91 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual volume = 198.2 mL
error = 200 - 198.2 = 1.8
So we have
We have the final answer as
<h3>0.91 %</h3>
Hope this helps you
Answer: m/s^2 (metre per second square)
Explanation:
Acceleration is the rate of change in velocity per unit time. The standard unit of measurement for acceleration is m/s^2 (metre per second square).
It can be derived from:
Acceleration = velocity / Time
Acceleration = (metre per second / second)
Acceleration = metre per second square.
In short form, it is written as m/s^2
