It would be to change the amount of solute or solvent in the solution.
Answer:
In glucose there are 6 carbon atom, atomic weight carbon is 12, so the molar mass is 72 and the percentage composition of carbon in C6H12O6=(72180)×100%=40% percentage by the mass.
Answer:
with four significant digits.
Explanation:
Given,
= 178.5 KJ/mole = 178500 J/mole (1kJ=1000J)
= 161.0 J/mole.K
According to Gibbs–Helmholtz equation:

= Gibbs free energy
= enthalpy change
= entropy change
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
As per question the reaction is spontaneous that means the value of
is negative or we can say that the value is less than zero.
Thus



Significant figures are the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Thus the temperature is
in kelvins above which this reaction is spontaneous.
Answer:
The only reule here that is applicable to substracting two values that have different numbers of decimal places is that The answer has the same number of decimal places as the least precise value
