This is because the relative atomic mass is the sum of the no of protons and neutrons while the atomic no is of the former only. it is not a whole number it is th average weighted masses of the various isotopes of the element multiplied by their corresponding relative abundance. pls thank me and mark me briniest

How many grams of hcl can dissolve in 200 g of water at 60 c?
Eddi Din [679]

The solubility curve is a plot of solubility against temperature.

<h3>What is solubility?</h3>

The term solubility refers to the amount of substance that dissolves in solution at a given temperature. Hence, the solubility curve is a plot of solubility against temperature.

Thus, from the solubility curve (not shown) the amount if HCl dissolved can be obtained hence the question is incomplete.

What is the standard entropy change for the reaction below? 2 CO(g) + 2 NO(g) → N2(g) + 2 CO2(g) S o (CO(g)) = 197.7 J/(mol·K) S
photoshop1234 [79]

Answer:

\Delta _RS^o=-230J/(mol*K)

Explanation:

Hello,

In this case, for the given chemical reaction:

2 CO(g) + 2 NO(g) \rightarrow N_2(g) + 2 CO_2(g)

The standard entropy change is computed by subtracting the products standard enthalpy and the reactants standard enthalpy considering each species stoichiometric coefficients:

\Delta _RS^o=S ^o_{N2(g)}+2S ^o_{CO2(g)}-2S ^o_{CO(g)}-2S ^o_{NO(g)}\\\\\Delta _RS^o=191.6J/(mol*K)+2*213.8J/(mol*K) -2*213.8J/(mol*K) -2*210.8J/(mol*K)\\\\\Delta _RS^o=-230J/(mol*K)

Best regards.
