Calculate the molarity of a solution made by

Chemistry
1 answer:
Kazeer [188]3 years ago
4 0

Answer:

0.1933 M

Explanation:

Data provided in the question:

Number of Moles of Na₂SO₄ initially taken = 0.145 mol

Volume of solution, V = 750 mL = 0.750 L

Now, the molarity is given as:

Molarity = \frac{\textup{moles of solute}}{\textup{volume of solution in liter}}

or

Molarity = \frac{0.145}{0.750}

or

Molarity = 0.1933 M

7. What volume of a 0.10 mol/l HCl solution is needed to neutralize 10 ml of a 0.15
svp [43]

Answer: The volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml

Explanation:

To calculate the volume of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HCl

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is LiOH.

We are given:

n_1=1\\M_1=0.10mol/L\\V_1=?mL\\n_2=1\\M_2=0.15mol/L\\V_2=10mL

Putting values in above equation, we get:

1\times 0.10\times V_1=1\times 0.15\times 10\\\\V_1=15mL

Thus the volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml

When a mixture of oxygen and hydrogen is ignited in a test tube, the reaction shown occurs. Hydrogen + Oxygen → Water + Energy S
grin007 [14]

Answer:

products

Explanation:

In chemistry, chemical reactions is the combination of two or more substances to yield other substances. The substances that react is called REACTANTS while the substances formed after the reaction is called PRODUCTS.

According to this question, a mixture of oxygen and hydrogen is ignited in a test tube as follows:

Hydrogen + Oxygen → Water + Energy

In this reaction, the substances being combined (usually found on the left side of the equation) are hydrogen and oxygen. Hence, oxygen and hydrogen are REACTANTS. Also, the substances produced as a result of the reaction is water (H2O). The PRODUCTS of the reaction is WATER.
