How much work (in J) is involved in a chemical reaction if the volume decreases from 5.35 to 1.55 L against a constant pressure
Mrac [35]

Answer:- work = 319 J

Solution:- The volume of the gas decreases from 5.35 L to 1.55 L.

\Delta V=1.55L-5.35L  = -3.80 L

external pressure is given as 0.829 atm.

w=-P_e_x_t\Delta V

where w is representing work.

Let's plug in the values and calculate pressure-volume work:

w=-0.829atm(-3.80L)

w = 3.15 atm.L

We need to convert atm.L to J.

1 atm.L = 101.325 J

So, 3.15atm.L(\frac{101.325J}{1atm.L})

= 319 J

So, 319 J of work is involved in a chemical reaction. Positive work means the work is done on the system.

Find the density of a sample that has a volume of 36.5L and a mass of 10.0kg
lara31 [8.8K]
  • Answer:

<em>≈ 0,27 g/cm³</em>

  • Explanation:

<em>36.5 l = 36.5 dm³ = 36500 cm³</em>

<em>10 kg = 10000 g</em>

<em>d = m/V</em>

<em>= 10000g/36500cm³</em>

<em>≈ 0,27 g/cm³</em>
