Answer:

P(total) = 6.2 atm

Explanation:

Given data:

Pressure of nitrogen = 2.5 atm

Pressure of argon = 3.7 atm

Final pressure = ?

Solution;

According to Dalton law of partial pressure,

The total pressure exerted by mixture of gas is equal to the sum of individual pressure of each gas present in mixture.

Mathematical expression:

P(total) = P₁ + P₂+.... Pₙ

Now we will put the values in formula:

P(total) = P₁ + P₂

P(total) = 2.5 atm + 3.7 atm

P(total) = 6.2 atm

What is the molarity of a solution containing 8.0 moles of solute in 120mL of solution?
Nataliya [291]
Answer:
200/3 M which is approximately equal to 66.6667 M

Explanation:
Molarity is defined as the number of moles of solute per liter of solution.

It can be calculated as follows:
molarity =  \frac{number of moles of solute}{liters of solution}

We are given that:
number of moles of solute = 8 moles
volume of solution = 120 ml = 0.12 liters

Substitute with the givens in the above equation to get the molarity as follows:
molarity = \frac{8}{0.12} =  \frac{200}{3} = 66.6667 M

Hope this helps :)

The ccl4 formed in the first step is used as a reactant in the second step. if 2.00 mol of ch4 reacts, what is the total amount
Leni [432]
<span>CH4 + 4 Cl2 → CCl4 + 4 HCl (4.00 mol CH4) x (1/1) x (0.70) = 2.80 mol CCl4 (4.00 mol CH4) x (4/1) x (0.70) = 11.2 mol HCl CCl4 + 2 HF → CCl2F2 + 2 HCl (2.80 mol CCl4) x (2/1) x (0.70) = 3.92 mol HCl 11.2 mol + 3.92 mol = 15.1 mol HCl from both steps</span>

A monatomic ideal gas that is initially at 1.50 * 105 Pa and has a volume of 0.0800 m3 is compressed adiabatically to a volume o
lubasha [3.4K]

Answer:

300000Pa or 3×10^5 Pa

Explanation:

Since the problem involves only two parameters of volume and pressure, the formula for Boyle's law is suitably used.

Using Boyle's law

P1V1 = P2V2

P1 is the initial pressure = 1.5×10^5Pa

V1 is the initial volume = 0.08m3

P2 is the final pressure (required)

V2 is the final volume = 0.04 m3

From the formula, P2 = P1V1/V2

P2 = 1.5×10^5 × 0.08 ÷ 0.04

= 300000Pa or 3×10^5 Pa.
