2.50 g of hydrogen gas is heated from 17.0 0C to 230C. The specific heat capacity of hydrogen is 14.267 J/g●0C. How much energy is absorbed?
a. 2.14 x 102 J
b. 2.14 x 102 kJ
c. 0.214 J
d. 0.214 kJ
To calculate the energy absorbed, we can use the formula:
Q = m * c * ΔT
Where:
Q is the energy absorbed
m is the mass of the hydrogen gas (2.50 g)
c is the specific heat capacity of hydrogen (14.267 J/g·°C)
ΔT is the change in temperature (230°C - 17°C = 213°C)
Plugging in the values into the formula:
Q = 2.50 g * 14.267 J/g·°C * 213°C
Q = 760.0575 J
So the amount of energy absorbed is 760.0575 J.
