Preparation of laboratory solutions

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.
!PLEASE BLESS FOR ME AND MY PARENTS!
