Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0L. What temperature must be maintained
Morgarella [4.7K]
Given:

P = 123 kPa
V = 10.0 L
n = 0.500 moles
T = ?

Assume that the gas ideally, thus, we can use the ideal gas equation:

PV = nRT

where R = 0.0821 L atm/mol K

123 kPa * 1 atm/101.325 kPa * 10.0 L = 0.500 moles * 0.0821 Latm/molK * T

solve for T 

T = 295.72 K<span />

The temperature of a sample of water increases from 20.9°C to 45.5°C as it absorbs 5637 J of heat. What is the mass of the sampl
djyliett [7]
Q = 5637 J

 C =4.814 J/KgºC

Temperature  : 45.5ºC - 20.9º C = 24.6ºC

Q = m x C  x T

5637 = m x 4.814 x 24.6

5637 = m x 118.4244

m = 5637 / 118.4244

m = 47.60 g

hope this helps!
