1.00 mole of solid NaOH is dissolved in 1.000 kg H2O. (b) A solution containing 1.000 mole of NaOH and 0.500 kg of H2O is mixed with one containing 0.500 mole of NaOH and 1.000 kg of H2O. E7.10 It has been shown that the equation ϕL−128.9mexpresses the relative apparent molar ...
The mass of a non-volatile solute of molar mass 40g mol−1 that should be dissolved in 114 g of octane to lower its vapour pressure by 20% is A10 g B11.4 g C9.8 g D12.8 gSubmit What will be the mass of a non-volatile solute ( Molar mass =40gmol−1) Which should be di...
To solve the problem, we need to find the mass of a non-volatile solute (with a molar mass of 60 g/mol) that must be dissolved in 100 g of water to decrease the vapor pressure of water by 25%. We will also calculate the molality of the resulting solution. 1. Identify the Initial...
What is the molar mass of octane? What is promethium's freezing point? What is the melting point of a pure substance? What is bond enthalpy? What is roentgenium's melting point? What does the specific heat of a substance represent? What is the molar mass of a compound? What is the ...
Heat Capacity of a body is defined as the amount of heat required to raise the temperature of the body through unit degree. The heat capacity of a body depends on its mass and the nature of the body. The SI unit of heat capacity is {eq}\text J\text K^{-1} {/eq}...
