The top number on elements in the periodic table is the atomic number, so when you look at the periodic table you can see that 42 is Mo (Molybdenum), and this is the only element with that atomic number.

The second volume : 42.2 L
<h3>Further explanation</h3>
Given
51.7 L at 27 C and 90.9 KPa
Required
The second volume
Solution
STP = P₂=1 atm, T₂=273 K
T₁ = 27 + 273 = 300 K
P₁ = 90.9 kPa = 0,897 atm
Use combine gas law :
P₁V₁/T₁ = P₂V₂/T₂
Input the value :
0.897 x 51.7/300 = 1 x V₂/273
V₂= 42.20 L
The number of particles in 46g of Sodium (Na) atoms are 2.00088735004 mol
Answer:
0.416moles
Explanation:
Using the formula;
number of moles = mass ÷ molar mass
Molar mass of CO2 = 12 + 16(2)
= 12 + 32
= 44g/mol
According to the information in this question, there are 18.3g of CO2
number of moles (n) = 18.3/44
= 0.4159
= 0.416moles of CO2
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
