The henry's law constant for helium gas in water at 30C is3.70x10-4 M/atm. when the partial pressure ofhelium above a sample of
water is 0.650 atm, the concentration ofhelium in the water is_______M.
a. 2.41 x 10-4
b. 3.70 x 10-4
c. 1.76 x 103
d. 5.69 x10-4
e. 1.30
1 answer:
Answer:
a. S = 2.41 x 10⁻⁴ M
Explanation:
The solubility S of a gas in water at a given temperature is given by the equation
S = Kp where S= solubility of the gas
K= Henry's Constant for the gas
p = partial pressure of the gas
solving for S
S = 3.70 x 10⁻⁴ M/atm x 0.650 atm =2.41 x 10⁻⁴ M

Answer:
The change in temperature that occurs when 8000 J of heat is used by a mass 75 g of water is 25.4 °C
Explanation:
H = mc ΔT
m = 75 g
c = 4. 200 J/ g °C
H = 8000 J
ΔT =?
Rearranging the formula, making ΔT the subject of formula;
ΔT = H / m c
ΔT = 8000 / 75 * 4.200
ΔT = 8000 / 315
ΔT = 25.4 °C
