Ammonia gas has a molar mass of approximately 17 grams per mole. At 290K and 1.2 atm, a sample of ammonia has a volume of 3.7 L.
jeka94

Ammonia gas will have a mass of 3.17grams.

HOW TO CALCULATE MASS:

  • The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass.

  • However, to calculate the number of moles present in the ammonia gas given in this question, we use the formula as follows:

  • PV = nRT

where;

  1. P = pressure (atm)
  2. V = volume (L)
  3. n = number of moles (mol)
  4. R = gas law constant
  5. T = temperature

n = PV ÷ RT

n = (1.2 × 3.7) ÷ (0.0821 × 290)

n = 4.44 ÷ 23.81

n = 0.186mol

  • Mass = 0.186 × 17

  • Mass of ammonia gas = 3.17g

  • Therefore, the mass of ammonia gas is 3.17grams.

can a light object that was hit with a small force accelerate as rapidly as a heavier object hit with a big force? why or why no
Tcecarenko [31]

The acceleration is defined by force divided by the mass of the object. So, When the smaller object is hit by a small force, it can produce equal acceleration which is same as that of the bigger body hit with large force.

<h3><u>Explanation:</u></h3>

Force is defined as the product of the mass of the body its applied to and the acceleration of the body in the direction of the force. So acceleration is force divided by the mass of the body.

Let the mass of the smaller body be m and that of the larger body be M.

The smaller force applied on the smaller body be f and the larger force applied on the larger body be F.

So acceleration of the larger body = F/M.

Acceleration of the smaller body = f/m.

For the accelerations to be same,

F/M = f/m.

Or F/f = M/m.

So when the ratio of the force applied on two bodies is in ratio of their masses, the acceleration becomes equal.

What is the difference between a physical and a chemical property? (please hurry)
natulia [17]
Chemical and physical properties are ways that scientists classify a substance. The color or mass it has are physical properties. However, chemical properties are chemical changes a substance undergoes.
