How do you you find the minimum mass of H2SO4?

Answer 1

Is the question to find the mm of H2SO4? If so then you are probably looking for the molar mass and not the minimum mass.

Look up each individual mass of each element in the periodic table and add together to get the molar mass.

Keep in mind that these are rounded differently according to what periodic chart you are looking at.

H=1.008 You have 2 in your formula so 1.008x2=2.016

S= 32.065 Only one of those in formula

O=16.00 Your have 4 of these in formula so 16.00x4=64.00

Now add together. 2.016+32.065+16.00= ??

mm or molar mass of H2SO4 is expressed as 50.081 amu

Answer 2

The molecular mass of this molecule (or compound) is obtained by adding up the atomic masses of all the elements present in the compound.

Hydrogen has an Atomic Mass of 1 unit (Approximate value) , Sulfur has an atomic mass of about 32 units (Estimated value) and Oxygen has an approximate atomic mass of 16 units.

There are 2 atoms of Hydrogen, 1 atom of Sulfur and 4 atoms of Oxygen in this compound. Thus the atomic mass of each element must first be multiplied by the number of atoms present and then it must be added.

I.e., (2x1) + (1x32) + (4x16) = 2 + 32 + 64

Which is equal to 98 units.

Thus the mass of the compound is 98 atomic units.

Note: This is an approximate value as the atomic masses of each element taken into consideration is approximate. For example, the actual atomic mass of Hydrogen and Oxygen is 1.008 ans 15.95 respectively. So the actual mass of this compound may differ by a number as small as 0.0001.
