Answer:
1.07×10²¹ molecules are needed to sound the alarm
Explanation:
Let's convert the mass of CO to moles, to determine the amount of molecules.
0.05 g . 1 mol / 28 g = 1.78×10⁻³ moles
Now we can determine the number of molecules with the NA
1 mol has 6.02×10²³ molecules
1.78×10⁻³ moles may have (1.78×10⁻³ . 6.02×10²³) / 1 = 1.07×10²¹ molecules
The answer is E.solution. I hope it helps. Please Brainly Me! It is the thing with the crown next to the stars.
Answer:
is there an option for silver? if so, silver is the answer.
Through the vibration of particles in a medium.
The answer to this question would be <span>na2so4.
Most of the metal on the first and second columns of the chemical table would have high water solubility. Silver(Ag) and iron(Fe) is a molecule that belongs to transition metal group, which did not have high solubility in the water. Na2SO4 would be the one with highest water solubility</span>
