The molecular weight of H2SO4 is 98. The amount of the acid present in 400ml of 0.1M solution
So
1 litre of 1 M contains 1 mole of the acid.
1 litre of 0.1 M contains 0.1 mole of the acid.
100 ml litre of 0.1 M contains 0.01 mole of the acid.
so 400 ml contains??
It may be 10ml 20ml 30ml 40ml
To calculate the amount of acid present in a solution, you need to use the formula:
Amount (in moles) = Concentration (in moles per liter) x Volume (in liters)
Given:
Concentration of the solution = 0.1 M
Volume of the solution = 400 ml = 0.4 L
Step 1: Convert the volume from milliliters (ml) to liters (L).
To convert milliliters to liters, divide the volume by 1000:
0.4 L = 400 ml / 1000
Step 2: Plug the values into the formula.
Amount (in moles) = 0.1 M x 0.4 L
Step 3: Calculate the amount of acid.
Amount (in moles) = 0.04 moles
So, in 400 ml of a 0.1 M solution of H2SO4, there are 0.04 moles of the acid.
