a chemistry teacher adds 50.0 ml of 1.50 m h2so4 solution to 200 ml of water. What is the concentration of the final solution?
nevsk [136]

Answer:0.300M

Explanation:1) Data:

a) Initial solution

M = 1.50M

V = 50.0 ml = 0.050 l

b) Solvent added = 200 ml = 0.200 l

2) Formula:

Molarity: M = moles of solute / volume of solution is liters

3) Solution:

a) initial solution:

Clearing moles from the molarity formula: moles = M × V

moles of H₂SO₄ = M × V = 1.5M × 0.050 l = 0.075 mol

b) final solution:

i) Volumen of solution = 0.050 l + 0.200l = 0.250l

ii) M = 0.075 mol / 0.250 l = 0.300M ← answeer

How many moles of calcium oxide are formed when 3 moles of calcium react with oxygen?
Temka [501]

Answer:

3 moles of CaO

Explanation:

The chemical balanced equation is;

2Ca + O₂ → 2CaO

The ratio of calcium(Ca) to Calcium Oxide(Cao) in this equation is 2:2.

Now, when 3 moles of calcium react with oxygen, Cao produced will be;

3 moles of O₂ × 2 moles of CaO/2 moles of Cao = 3 moles of CaO
