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
Answer:
0.11 atm
Explanation:
Given data
- Temperature (T): -16 °C + 273.15 = 257 K
- Ideal gas constant (R): 0.082 atm.L/mol.K
First, we will calculate the moles (n) of sulfur hexafluoride, considering its molar mass is 146.06 g/mol.
34 g × (1 mol/146.06 g) = 0.23 mol
Then, we can calculate the pressure (P) of sulfur hexafluoride using the ideal gas equation.
P × V = n × R × T
P = n × R × T / V
P = 0.23 mol × (0.082 atm.L/mol.K) × 257 K / 45 L
P = 0.11 atm

Explanation:
hope this helps! :D
If element X has 59 protons then element X has 59 electrons.
Side note: as long as an element stays an atom the number of protons and electrons will always have the same value.
Answer:
c
Explanation:
we cannot say that either will die out, because we dont know the conditions. but we know that both sides out the mountian arent exactly the same, so we know they will evolve to adapt and grow with what they have
