The answer is 2.95 × 10²³ atoms
Atomic mass is 200.59 g.
So, 1 mole has 200.59 g. Let's calculate how many moles have 98.3 g:
1M : 200.59g = x : 98.3g
x = 98.3 g * 1 M : 200.59 g = 0.49 M
To calculate this, we will use Avogadro's number which is the number of units (atoms, molecules) in 1 mole of substance:
6.023 × 10²³ atoms per 1 mole
<span>How many atoms are in 0.49 mole:
</span>6.023 × 10²³ atoms : 1M = x : 0.49M
x = 6.023 × 10²³ atoms : 1M * 0.49M = 2.95 × 10²³ atoms
Answer:
A
Step-by-step explanation:
Let's check
The formula is 3 *6^(n-1)
The first generation had 3 rabbits
3*6(1-1) = 3*6^0 = 3*1 =3
That works
Try it again with the 2nd generation
n is the number of generation
3*6^(2-1)= 3*6^1 = 18
●●●●●●●●●●●●●●●●●●●●●
We can deduce the formula
The initial number of rabbits is 3
Each time we multiply by 6
So for the generation number n the formula will be :
3*6^(last generation-first generation)
3*6^(n-1)
Answer:
x=28
Step-by-step explanation:
|28-x|=0
|28-28|=0
x=28
C. (2/5)^2 * n^9*2
4/25n^18
Answer: 7:10
Step-by-step explanation: You are asked to find the ratio of sweaters to pairs of jeans. All you do is write the 7 sweaters and the 10 pairs of jeans. And you get a ratio of 7:10. Since this cannot be reduced any further, you just leave it as it is.
Hope this helps.
