The answer to this would be:
The shuttle can carry a maximum of 4 astronauts for one mission.
2 LiOH + CO2 -----> Li2CO3 + H2O
(3.50 × 10^4 g LiOH) (1 mol LiOH/ 24 g LiOH) ( 1 mol CO2 / 2 mol LiOH) ( 44 g CO2 /1 mol CO2) = 32, 083.33 g CO2
32, 083.33 g / 9 (8.8 × 10^2) = 4
<span>I think it's HgNO3 because the subscripts on Hg and No3 are divisible by 2 :)

Answer:
291.72 grams of magnesium metal will react completely with 4.8 liters of 5.0 M HCl.
Explanation:
Molarity of teh HCl solution = 5.0 M
Volume of HCl solution = 4.8 L
Moles of HCl = 24 moles
According to reaction , 2 moles of HCl reacts with 1 mole magnesium.
Then 24 moles of HCl will react with:
of magnesium
Mass of 12 mol of magnesium =24.31 g/mol × 12 mol = 291.72 g
291.72 grams of magnesium metal will react completely with 4.8 liters of 5.0 M HCl.

Answer is: the amu of a sodium atom is 23.
The unified atomic mass unit (amu) is a standard unit of atom mass.
One unified atomic mass unit is approximately the mass of one nucleon (proton or neutron).
The unified atomic mass unit is equal 1.66·10⁻²⁷ kg.
n(p⁺) = 11; number of protons in sodium atom.
n(n°) = 12; number of neutrons of sodium atom.
n(p⁺ + n°) = 11 + 12.
n(p⁺ + n°) = 23; number of nucleons in sodium atom.
