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 :)
Answer:
a large area where the topography is made up of one landform .
Explanation:
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.
