Answer:

400.197mmHg

Explanation:

P1V1 / T1 = P2V2 / T2

Where P1=524 mm Hg V1 =275 ml T1 = 35°C +273 = 308k

V2= 325-ml T2= 5°C+273 = 278k , P2= ?

Substituting the values into the formula.

524 mm Hg ×275 ml /308k = P2×325-ml/278k

Cross multiply

524 mm Hg ×275 ml×278k=308k×P2×325-ml

40059800= 100100×P2

P2 = 40059800/100100

P2= 400.197mmHg

Hence, the second pressure will be 400.197mmHg

Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, how many
prisoha [69]

337.92 moles of Ozone will be produced

1 Oxygen atom is 8 g

1 mole of ozone, O3 = 8 * 3 = 24 g

7.92 * 1024 = 8110.08 g

1 mole = 24 g

? moles = 8110.08 g

? = 337.92 moles
