Answer:
SO has about 0.52 moles, while NO has about 0.83 moles
Explanation:
To calculate the number of moles of a certain molecule, you first need to figure out that molecule's molar mass. For SO, the molar mass is the mass of sulfur combined with the mass of oxygen. 16 + 32=48. For NO, you do a similar thing but with nitrogen. 16+14=30. From here, you can simply divide. 25 grams divided by SO's molar mass of 48 yields about 0.52 moles, while for NO there is about 0.83 moles. Hope this helps!
PH= log[H3O+]
10.25=log [H3O+]
[H3O+] = 10^10.25
[H3O+]= 1.778 ×10^10
