The mass that the aerogel insulation added to the aircraft, with respect to glass, is 8.8 × 10³ g.
The density of the aerogel is 0.00011 lb/in³. We will convert it to g/cm³ using the following conversion factors:
If the maximum space for insulation in the spacecraft's hull was 2921 cm³, the mass that would occupy the aerogel with a density of 0.0030 g/cm³ is:
Glass is about 1000 times denser than aerogel. That is,
If the maximum space for insulation in the spacecraft's hull was 2921 cm³, the mass that would occupy the glass with a density of 3.0 g/cm³ is:
The mass that would add the aerogel with respect to the glass is:
The mass that the aerogel insulation added to the aircraft, with respect to glass, is 8.8 × 10³ g.

Explanation:
An equilibrium constant of the reaction is the ratio of the concentrations of the products to the concentration of the reactants raised to their power equal to stoichiometrc coefficients in a balanced chemical equation.
Equilibrium constant equation for the reaction of acetic acid with water.
The equilibrium constant of the above reaction will written as:
That would be the crust (outer layer), mantle (semi-molten inner layer) and finally the core (the solid iron core of our planet). hope i helped :)
Answer: 5 water molecules
Explanation:
Decomposition of hydrated copper sulphate is given by:
Molar mass of = 159.6 g/mol
According to stoichiometry:
(159.6+18x) g of decomposes to give = 159.6g of
Thus 7.74 g of decomposes to give= g
But it is given 7.74 g of a sample of hydrated salt was found to contain 4.95 g of anhydrous salt.
Thus we can equate the two equations:
x=5
Thus there are 5 water molecules associated with each formula unit.
