Question

Volume occupied by 2.5 g of o2 at 27 degrees c and 760 mm og hg

Answer 1

Step-by-step explanation:

. volume of 32 g of oxygen gas = 22400 ml at STP

. Volume of 2mg of oxygen gas = 0.002/32 x22400 = 1.4 ml at STP .

. Volume of the gas at 27° c and 760 mm pressure is

. =760 x1.4 /273 =760x/300

. so v= 1.4 x 300/273

. = 1.538~=1.54ml of oxygen.

Answer 2

Answer:

V≈1.953

Step-by-step explanation:

PV=nRT

1×V=(2.5/32)×(1/12)×300

V≈1.953
