The mass of lactic acid for each quantity is:
0.1 mol: 9.01 g
0.2 mol: 18.02 g
0.5 mol: 45.04 g
1.0 mol: 90.08 g
To calculate the mass of lactic acid, we need the following information:
Molar mass of lactic acid: 90.08 g/mol
Quantities of lactic acid: You haven't provided specific quantities, so let's assume we have 0.1, 0.2, 0.5, and 1.0 moles of lactic acid.
Using the formula mass = moles x molar mass, we can calculate the mass of each quantity:
For 0.1 mol:
mass = 0.1 mol x 90.08 g/mol = 9.01 g
For 0.2 mol:
mass = 0.2 mol x 90.08 g/mol = 18.02 g
For 0.5 mol:
mass = 0.5 mol x 90.08 g/mol = 45.04 g
For 1.0 mol:
mass = 1.0 mol x 90.08 g/mol = 90.08 g
Question:-
What is the mass in grams of 0.1, 0.2, 0.5 and 1 mol each quantity of lactic acid (C_3 H_6 O_3 , molar mass 90.08g / m * ol ), the compound responsible for the aching feeling of tired muscles during vigorous exercise?
