Answer:
Density = 1000 g/l
= 1.00 kg/l.
Molality = 0.037 mol/g
= 37 mol/kg.
Explanation:
Molar concentration of nitric acid = 15.9 M.
Mass of water in 100 g = 100 - 70
= 30 g
Mass of nitric acid = 70 g
Molar mass of HNO3 = 1 + 14 + (16*3)
= 63 g/mol
Number of moles = mass/molar mass
= 70/63
= 1.11 mol.
Molar concentration = number of moles/volume
Volume = 1.11/15.9
= 0.07 l
Density = mass/volume
Density =
= 70 * 0.07
= 1000 g/l
= 1.00 kg/l
Molality = number of moles of nitric acid/mass of solvent(water)
= 1.11/0.030
= 37 mol/kg
Answer:
It has a full outer shell and cannot incorporate any more electrons into the valence shell. ... The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas.
Mass of CO₂ produced : 58.67 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
CS₂ + 3O₂ -------> CO₂ + 2SO₂
mol of CO₂ based on mol of O₂ as a limiting reactant(CS₂ as an excess reactant)
From the equation, mol ratio of mol CO₂ : mol O₂ = 1 : 3, so mol CO₂ :
mass CO₂ (MW= 44 g/mol) :
