How many moles are present in 1.2L of a 0.1 M NaCl solution?

Chemistry
1 answer:
____ [38]3 years ago
8 0

Answer:

0.12 mole.

Explanation:

From the question given above, the following data were obtained:

Molarity of NaCl solution = 0.1 M

Volume of NaCl solution = 1.2 L

Mole of NaCl =.?

Molarity of a solution is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:

Molarity = mole /Volume

Thus, we can obtain the mole of NaCl in the solution by using the above formula as follow:

Molarity of NaCl solution = 0.1 M

Volume of NaCl solution = 1.2 L

Mole of NaCl =.?

Molarity = mole /Volume

0.1 = mole of NaCl /1.2

Cross multiply

Mole of NaCl = 0.1 × 1.2

Mole of NaCl = 0.12 mole

Therefore, 0.12 mole of NaCl is present in the solution.

How many grams of As2S3 are in 3.25 moles?
laiz [17]

Answer:

Explanation:

Molar mass of As2S3= {75(2) + 32(3)}

= 150 + 96 = 246g/mol

Amount = 3.25mole

And

Amount = mass/ molar mass

mass = amount × molar mass

Mass = 3.25 × 246

mass = 799.5g

What is the temperature of 4.5 moles of a gas that occupies 50. mL at 1.35 atm?
devlian [24]

Answer:

T = 0.182 Kelvin

Explanation:

As we know that

PV = nRT\\

Where P is the pressure in atmospheric pressure

T is the temperature in Kelvin  

R is the gas constant  

V is the volume in liters

R = 0.08206

Substituting the given values in above equation, we get -

1.35 * \frac{50}{1000}= 4.5 * 0.08206* T\\

On rearranging, we get

T = \frac{1.35*50}{1000*0.08206*4.5} \\

T = 0.182 Kelvin
