C.
because a, b, and d aren't porportional
but c x is divided by 2
Answer: a because it’s using the commutative property of addition meaning it’s the same mathematical statement, it’s just moved around
Step-by-step explanation:
Answer:
The measure of angle 1 is 55.
Step-by-step explanation:
The top angle= 75 because of the vertical angle theorem
The right angle= 50 because of the alternate exterior angle theorem
75+50=125
There are 180 degrees in a triangle so the angle has to equal 55
Answer:
x=50
Step-by-step explanation:
65+65=130
180-130=50
The number of particles the compound consists of is 7.65 × 10²⁴.
It is given that
no of moles n = 12.7
as we know the formulae for the number of particles
N=n× Nₐ
where Nₐ is Avogadro's Number.
n is the number of moles.
<h3>what is Avogadro's Number?</h3>
Avogadro's Number is the number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 10²³.
Therefore, the number of particles N= 12.7 × 6.02214076 × 10²³.
N=7.65 × 10²⁴
