If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.
therefore there’s 3 electrons and 3 protons
1 mole C6H12O6 -------------- 180.15 g
? moles C6H12O6 ------------ 523.46 g
523.46 x 1 / 180.15 => <span>2.905 moles</span>
Answer:
It is used as a refrigerant.
It is used for fire extinguisher
POH = -log[OH-]
pH + pOH = 14 (at 25 degrees celsius)
pOH = -log(5.4*10^-4) = 3.27
pH = 14 - 3.27 = 10.73
The pH of a solution with a hydroxide ion concentration of 5.4*10^-4 M is 10.73.
