There are 1.86 x 10²⁴ molecules of Silicon dioxide, SiO₂
<h3>Further explanation
</h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
Moles can also be determined from the amount of substance mass and its molar mass
1 mol = 6.02.10²³ particles
Can be formulated
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
3.09 mol of Silicon dioxide, SiO₂
n=mol=3.09
They are mostly made of gas
They have rings
They have thick atmospheres
I hope this helps.
This is mind numbing, but I got you.
3NaOH + 1FeCl<em>3</em> = 1Fe(OH)<em>3 </em>+ 3NaCl
3Mg + 2H<em>3</em>(PO)<em>4</em> = 1Mg(PO<em>4</em>)<em>2</em> + 3H<em>2</em>
After the first 30 minutes,
dT = 75-60
= 15
dt = 30 mins
k = (15/60) * (60 - 38)
k = 5.5
After 60 minutes,
dT = 60 - T
dt = 30
(60 - T)/30 = 5.5(T - 38)
60 - T = 165T - 6270
166T = 6330
T = 38.13°F
Answer:
number of hydrates (H₂O ) = 6
Explanation:
Data Given:
moles of BaCl₂ = 0.0016
moles of H₂O = 0.0096
number of hydrates = ?
Solution:
As we have moles of BaCl₂ and H₂O water.
First find the simplest ratio of BaCl₂ and H₂O
Ratio BaCl₂ : H₂O
0.0016 : 0.0096
Now divide the ratio on smallest number to get simplest ratio
BaCl₂ : H₂O
0.0016 / 0.0016 : 0.0096 / 0.0016
1 : 6
So,
The ratio of BaCl₂ to water (H₂O) is 1 to 6. it means there are 6 water molecules are present.
The formula of hydrated Barium Chloride will be
BaCl₂. 6H₂O
So the number of hydrates will be 6
