Explanation:

The mass of Cs present in 15.0 g of caesium acetate is approximately 10.18 grams.

To calculate the mass of Cs (caesium) present in 15.0 g of caesium acetate ([tex]\rm CsCH_3COO[/tex]), you need to determine the molar mass of [tex]\rm CsCH_3COO[/tex] and then find the proportion of Cs in the formula.

Molar mass of [tex]\rm CsCH_3COO[/tex]:

Cs: 1 atom * atomic mass of Cs = 1 * 132.91 g/mol = 132.91 g/mol

C: 2 atoms * atomic mass of C = 2 * 12.01 g/mol = 24.02 g/mol

H: 6 atoms * atomic mass of H = 6 * 1.01 g/mol = 6.06 g/mol

O: 2 atoms * atomic mass of O = 2 * 16.00 g/mol = 32.00 g/mol

Total molar mass of [tex]\rm CsCH_3COO[/tex] = 132.91 + 24.02 + 6.06 + 32.00 = 194.99 g/mol

Now, find the proportion of Cs in the formula:

Mass of Cs in 1 mol of [tex]\rm CsCH_3COO[/tex] = 132.91 g/mol

Mass of Cs in 15.0 g of [tex]\rm CsCH_3COO[/tex] = (15.0 g * 132.91 g/mol) / 194.99 g/mol ≈ 10.18 g

Thus, the mass of Cs present in 15.0 g of caesium acetate is approximately 10.18 grams.

Answer:

Law of conservation of linear momentum :- when there is no any external force applied on a system of particles then , momentum of system of particles will be conserved or you can say that if external force is zero. Then momentum of system of particles in intially = momentum of system of particles in finally

Explanation:

According to Newton's second law of motion, because no external force occurs on the system, The change in momentum is equal to zero; hence, the linear momentum is conserved. The entire linear momentum of an isolated system, that is, a system that is not subjected to any external forces, is conserved.

1. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

2. It must be conserved in an isolated system because isolated systems do NOT exchange matter or energy with their surroundings.

The total pressure of the system is equivalent to the sum of all the pressure of the individual gases. The total pressure of the flask is 2.37 atm.

According to Dalton's law, the total pressure of the system will be equivalent to the total of the pressures exerted by the individual gases present in the system.

The total pressure of gases is given as,

[tex]\rm P = P_{1} +P_{2}+ P_{3}.....P_{n}[/tex]

Given,

Substituting values in the above equation:

[tex]\begin{aligned}\rm P &= 0.72 + 1.65\\\\&=2.37\;\rm atm\end{aligned}[/tex]

Therefore, 2.37 atm is the total pressure of the flask.

Explanation:

3.Apply the ideal gas law: PV = nRT solving for n. Here you can use the pressure given in atm, but you must choose the 0.0821 atm L/mole K gas constant. Or you can change 4.5 atm to 3420 mm Hg and use the 62.4 mmHg L/mole K gas constant. You must change 500 ml to 0.5 L because both gas constants have units in L, and so the volume must be in liters so it can cancel out. And of course, you must change the temperature to Kelvin.

a. n = (4.5atm)(0.5L)
