Consider an ideal gas that exerts a pressure of 23.76 mmHg at 25°C. Assuming n and V are held constant, what would its pressure be at 40°C? 70°C? 100°C? Compare the numbers you have just calculated with the vapor pressures of water (look up online or in reference books) at these temperatures. Suggest a reason why the two sets of numbers are so different.

lol for the pointsss

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
