Explanation:
First we need to calculate the number of moles of FeS
:
number of moles = mass (grams) / molecular mass (g/mol)
number of moles of FeS
= 198.2/120 = 1.65 moles
From the chemical reaction we deduce that:
if 4 moles of FeS
produces 8 moles of SO
then 1.65 moles of FeS
produces X moles of SO
X = (1.65×8)/4 = 3.3 moles of SO
Now we can calculate the mass of SO
:
mass (grams) = number of moles × molecular mass (grams/mole)
mass of SO
= 3.3×64 = 211.2 g
Answer:
11
Explanation:
The atomic number = number of protons. The mass number (23) = sum of number of neutrons and protons. Since you know the mass number is 23 and it has 12 neutrons, 23-12 gives you 11 protons, so its atomic number is 11.
