For prepration of 0.1M H2SO4 in 500ml of solution.
First of all find molar mass of sulfuric acid
H= (1 ×2) = 2
S= 32
O= (16 ×4) = 64
Total = 98

Formula:
molarity=(mass in gram/molecular mass) × 1/1liter
Put the values
0.1=mass in gram/98 × 1/0.5
0.1 ×98 ×0.5 = mass in grams
4.9 = mass in gram

Now find the percentage purity of H2SO4 we have generally 98 % pure sulpuric acid
mass=98/100 X 4.9
= 4.8
Now put the formula of Density to find volume
d = m/v
v =m/d Density of sulpuric acid is 1.8
v =4.8/1.8
=2.6ml

Now take cylindrical flask put 2.6ml sulfuric acid and fill up to 500ml.
Now your solution of 0.1m H2SO4 in 500ml is ready.
