Answer:
0.00663 grams/liter
Explanation:
HCl is a mineral acid with a molar mass of 36.46 g/mol.
No. of moles= mass/RMM
Making mass the subject of the formula:
Mass=Number of moles × RMM
Therefore 0.00040 mol HCl has a mass of:
0.00040 mol × 36.46 g/ mol
=0.01458 grams.
0.01458 grams are in 2.2 liters, Therefore 1 liter will have
0.01458 grams/2.2 liters= 0.00663 grams
concentration= 0.00663 grams/liter
