Answer:
The minimum mass of ethylene glycol = 6.641 Kg
Explanation:
Where T_f = freezing point of pure solvent water, 0°C
T_f'= Freezing point of solvent after mixture
K_f = Freezing point depression constant = 1.86 °C/m
Moecular weight of ethylene glycol = 60 g/mol
Weight of ethylene glycol = 14.5 Kg= 14.5×10^3 g
molality of ethylene glycol
Substitute the values to calculate m
by formula
calculating we get w = 6641.93 g
Therefore, The minimum mass of ethylene glycol = 6.641 Kg

Answer:
The correct answer is 66.1 g
Explanation:
According to <em>Law of Conservation of the Mass</em>, the mass of an isolated system is neither created or destroyed during chemical reactions. It is transformed. So, in a chemical reaction, the atoms of reactants are reoganizated by forming other compounds but the mass is conserved. Thus, the total mass of reactants is always equal to the total mass of products. If 23.6 g of a substance reacts with 42.5 g of another substance, the total mass of the products will be equal to the total mass of reactants:
23.6 g + 42.5 g = 66.1 g reactants = 66.1 g products
Both strong acid and strong base will alter the solubility and the nature of a protein. This is because, adding a strong acid or base to a protein will drastically change the pH of the protein and this will leads to formation of precipitation and denaturation of the protein.
