The formula wt of h2so4 is98bthe wt of the acid in 400ml of 0.1M solution is
To find the weight of sulfuric acid (H2SO4) in a 0.1M solution, we should first calculate the number of moles of acid present in the solution. The molecular weight of sulfuric acid (H2SO4) is 98 g/mol.
Given:
Volume of solution (V) = 400 mL = 0.4 L
Molarity of solution (M) = 0.1 M
Now, to find the number of moles (n) of acid present in the solution, we can use the formula:
n = M × V
Plugging in the values:
n = 0.1 M × 0.4 L
n = 0.04 moles
Finally, to find the weight of the acid, we can multiply the number of moles by the molecular weight:
Weight (wt) = n × molecular weight
Weight (wt) = 0.04 moles × 98 g/mol
Weight (wt) = 3.92 grams
Therefore, the weight of sulfuric acid in a 400 mL of 0.1M solution is 3.92 grams.
