the formula weight of h2so4 is 98. the weight of the acid in 400ml of 0.1M so the solution is?
mols H2SO4 in the solution is M x L = 0.400 x 0.1 = 0.04
grams = mols x molar mass = 0.04 x 98 = 3.92g
To find the weight of the acid in 400 mL of 0.1 M sulfuric acid (H2SO4) solution, we can use the formula:
Weight of acid (in grams) = Volume of solution (in liters) x Concentration of solution (in moles per liter) x Formula weight of the acid
First, we need to convert the volume of the solution from milliliters to liters. Since 1 liter is equal to 1000 milliliters, we can use the following conversion:
400 mL = 400 / 1000 = 0.4 L
Now, we can substitute the values into the formula:
Weight of acid = 0.4 L x 0.1 M x 98 g/mol
Weight of acid = 0.4 x 0.1 x 98 = 3.92 grams
Therefore, the weight of the acid in 400 mL of 0.1 M sulfuric acid solution is 3.92 grams.
To find the weight of the acid in the solution, we can use the formula:
Weight of acid = Volume of solution (in L) x Molarity of acid x Formula weight of acid
Given:
Volume of solution = 400 mL = 400/1000 L = 0.4 L
Molarity of acid = 0.1 M
Formula weight of H2SO4 = 98 g/mol
Substituting the values into the formula, we have:
Weight of acid = 0.4 L x 0.1 M x 98 g/mol
Calculating this expression gives us:
Weight of acid = 3.92 g
Therefore, the weight of the acid in 400 mL of 0.1 M H2SO4 solution is 3.92 grams.
