Question

20. At 25°C and 730 mm pressure, 380 mL of dry
oxygen was collected. If the temperature is
constant, what volume will the oxygen occupy at
760 mm pressure?
(a) 265 mL (b) 365 mL (c) 569 mL (d) 621 mL​

Answer 1

Answer:

b 365

= p2 v2

730 × 380 = 760 × x

277400 = 760 x

Explanation:

p1 v1 = p2 v2

730 × 380 = 760 × x

277400 = 760 x

x = b 365
