1.64 + 4.66 = 6.3
1.64/6.3 = 0.2603174603 = 26%

Answer : The percentage of salt in the mixture is 73.65 %

Explanation : Given,

Mass of salt = 1.64 lb

Mass of water = 4.66 lb

First we have to calculate the mass of mixture.

Mass of mixture = Mass of salt + Mass of water

Mass of mixture = 1.64 + 4.66 = 6.3 lb

Now we have to calculate the percentage of salt in the mixture.

Formula used :

\% \text{ of salt}=\frac{\text{Mass of salt}}{\text{Mass of mixture}}\times 100

Now put all the given vales in this formula, we get:

\% \text{ of salt}=\frac{4.64lb}{6.3lb}\times 100=73.65\%

Therefore, the percentage of salt in the mixture is 73.65 %

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
