Answer:
96g
Explanation:
Given parameters:
Number of moles of NaOH = 2.4moles
Unknown:
Mass of NaOH = ?
Solution:
The mass of a substance given the number of moles can be found using the expression below;
Mass of NaOH = Number of moles x molar mass;
Molar mass of NaOH = 23 + 16 + 1 = 40g/mol
Now input the parameters and solve;
Mass of NaOH = 2.4 x 40 = 96g
The taste of Acid is Sour, that of Base is Bitter and salt is salty. So, Pickle and Lemons give sour taste due to presence of Acids. The sour taste of Lemon is due to presence of Citric Acid in it. While the sour taste of Pickle is due to presence of Vinegar (5% Acetic Acid Solution). Vinegar is mainly used to prevent the Pickle from Bacterial Attack.
