Answer:
Brainliest pls
Explanation:
1 mole of a substance contains Avagadro’s number of particles,
i.e. 6.023*10^23
By unitary method,
5 moles of oxygen contains 5 times the Avagadro’s number of particles
i.e. 5* (6.023*10^23) = 3.0115*10^24 number of particles.
Now, the further answer depends on what particles the question concentrates on.
If number of atoms are asked , the above answer must be multiplied by 2, because oxygen is a diatomic gas and each atom contributes to be a particle.
therefore, 5 moles of oxygen has 6.023*10^24 atoms.
If number of molecules asked, the above answer is directly written...
Adenine pairs with Thymine and Guanine pairs with Cytosine. I remember this by the car (C) goes in the garage (G). Then A and T are the only ones left, so they pair together.
Answer:
<u><em>95 people can breath with five such trees supplying oxygen.</em></u>
Explanation:
Given data:
a man take in oxygen in a day : 22 
(1 = 1000L)
Tree length: 33 m
Tree diameter : 0.55 m
tree produce oxygen in a year : 84,000 L
Tree oxygen in the air : 20%
1 = 1000 L
To find:
number of people can breath with 5 such trees: ?
Calculation:
Calculate the oxygen produced by 5 trees:
= 5 x 84,000
= 420.000 L
= 420
Calculate the air
= 420 x 100% / 20%
= 2100 m^3
Calculate the number of people:
= 2100 m^3 / 22 m^3
= 95.5
= 95 people
