Answer:

The answer is 2.660 mol/l

Explanation:

Given: n= 0.0665, v= 25.00ml

Required: C

C (molarity)= n (of solute)/ v (of solvent) [ standard unit: mol/l]

First convert volume of solvent in its standard unit, i.e. litres(L)

v= 25.00ml/1000= 0.02500L

C = 0.0665 mol / 0.02500 L= 2.660 mL (In proper significant digits i.e. 4 sigdigs)

Therefore, The molarity of the sulfuric acid is 2.660 mol/L :)

Calculate the moles of SO2 that contains 3.8 moles of O atoms
Olegator [25]
Answer: 1.9 moles SO₂

Explanation:

1) The chemical formula SO₂ shows that for every mol of SO₂ there are 1 mol of S and two moles of O.

2) Then you can state the proportion between the number of moles of SO₂ and O to find how many moles of SO₂:contains 3.8 moles of O.


   1 mol SO₂                         x

-------------------- =   --------------------------

    2 moles O              3.8  moles O


3) Now, you can clear x:

x = 3.8 moles O × 1 mol SO₂ / 2 moles O.

x = 1.9 moles SO₂.
