Answer:

10 atm.

Explanation:

Using the combined gas law equation as follows;

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question,

P1 = 5 atm

P2 = ?

V1 = 4L

V2 = 2L

T1 = 25°C = 25 + 273 = 298K

T2 = 25°C = 298K

Using P1V1/T1 = P2V2/T2

5 × 4/298 = P2 × 2/298

20/298 = 2P2/298

Cross multiply

298 × 20 = 298 × 2P2

5960 = 596P2

P2 = 5960 ÷ 596

P2 = 10 atm.

How many moles of calcium are there in 5.74 x 1022 atoms of calcium?
igor_vitrenko [27]

Answer:

0.095 moles of Calcium is there in 5.74 x 1022 atoms of calcium.

Explanation:

  • As we know, 6.023*10^23 atoms of an element is equal to its atomic weight.

       And, 6.023*10^23 atoms of an element is also equal to 1 mole of the             element.

We have,

  • 6.023*10^23 atoms of element calcium equals to 1 mole of Calcium
  • 5.74*10^22 atoms of element calcium equals to

         (1/(6.023*10^.23)) * 5.74*10^22 moles of calcium

Therefore,

  • 5.74 x 1022 atoms of calcium= 0.095 moles of calcium.
