Answer: 1.4x10-3 g N2O4
Explanation: First convert molecules of N2O4 to moles using Avogadro's Number. Then convert moles to mass using the molar mass of N2O4.
9.2x10^18 molecules N2O4 x 1 mole N2O4 / 6.022x10²³ molecules N2O4
= 1.53x10-5 moles N2O4
1.53x10-5 moles N2O4 x 92 g N2O4/ 1 mole N2O4
= 1.4x10-3 g N2O4
Answer: avogadros number/constant
Explanation:
Answer:
<h2>Physical properties: H2SO4 is a colorless or slightly yellow viscous liquid with a pungent odor. It has a density of 1.84 g/mL, boiling point of 337 °C, and melting point of 10 °C. "Concentrated" sulfuric acid is 98% in water, and is the most stable form.</h2>
Answer:
Concentration of glyceraldehyde-3-phosphate is 0.0886mM
Explanation:
Get K from the expression exp(ΔG/-RT) = K
Where
ΔG = Gibbs free energy = 7.53 kJ/ mol = 7.53 * 10^3 J/mol
T = 250C = 273 +25 = 298 K
R = 8.3145 J(mol.K)
K = exp(7530/(-298*8.3145)
K = 4.79*10^-2
NB: K = (conc of products)/(conc of reactants)
From the question
dihydroxyacetone phosphate is the reactant while glyceraldehyde-3-phosphate is the product
4.70*10^-2 = (conc. Of products/1.85mM)
Conc of products = (4.70*10^-2)*1.85
Conc. Of products = 0.0886mM
Answer:
Because all the planets orbit the sun in the same direction, along a circular flattened disk.
