Problem

For a gold nucleus (A=197A = 197), estimate its mass using the following data: • Proportionality constant for nuclear radius R0=1.2 fmR_0 = 1.2\,\text{fm} • Average nuclear density ρ=2.3×1017 kg m−3\rho = 2.3 \times 10^{17}\,\text{kg}\,\text{m}^{-3} • 1 fm=10−15 m1\,\text{fm} = 10^{-15}\,\text{m} (i) Calculate the nuclear volume. (ii) Hence, find the nuclear mass (give your answer to two significant figures).
