Tatiana Booth · Answer 1

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
