In 1 mole of magnesium there are Avogadro's number of atoms are present.
Avogadro's number = 6.023 x 10²³
1 mole = 6.023 x 10²³ atoms
3.75 moles = 3.75 x 6.023 x 10²³
=2.26 x 10²⁴
So, in 3.75 moles of magnesium there are 2.26 x 10²⁴ atoms of magnesium are present.
Answer:
5.73 Liters
Explanation:
Pressure decreases => Volume increases (Boyles Law)
V(final) = 2.75L (750Torr/360Torr) = 5.73 Liters
Answer:
1.058337 grams of hydrogen and 2H2 + O2 ==> 2H2O hydrogen peroxide
mols H2 = grams/molar mass
Using the coefficients in the balanced equation, convert mols H2 to mols O2.
Now convert mols O2 to grams. That's grams mols O2 x molar mass O2.
and it could also produce H2O water but no air but it could make other things
