Answer:
The answer to your question is: Volume = 0.117 l
Explanation:
Data
V = ?
M = 9 x 10 ⁻²
mass = 1,9 g of KH₂AsO₄
MW KH₂AsO₄ = 39 + 2 + 75 + 64 = 180 g
Process
180 g of KH₂AsO₄ ------------------ 1 mol
1.9 g ------------------ x
x = 0.0011 mol of KH₂AsO₄
Molarity = # of moles / volume
Volume = # of moles / molarity
Volume = 0.0011 mol of KH₂AsO₄ / 0.09
Volume = 0.117 l = 117 ml
First, we need to find the amount of winks in an hour, to simplify it so we can answer easier. Since there are 60 minutes in an hour, we can multiply 5 by 60 to find the number of winks in an hour.
5*60=300
Now multiply 300 by 8.
300*8=2,400
She winks exactly 2,400 times per day.
Hope this helps!
Pneumonia is caused when an H3 is positive to any form so therefore the answer would be the element of a pneumonia will be a positive 6392
