Answer:
1.023 J / g°C
Explanation:
Mass, m = 37.9 g
Temperature increase (change) = 25.0°C
Heat = 969 J
Specific heat capacity , c= ?
The relationship between these quantities is given by the equation;
H = mcΔT
c = H / mΔT
c = 969 / (37.9 * 25)
c = 969 / 947.5 = 1.023 J / g°C
Mass = moles x molar mass
so mass of 6 moles of h2 is: 6×1×2 = 12g
4 protons the number of proton has the same number of electron [which is the same as atomic number]
