In 1906, a 600 g diamond was found at the Premier Mine in South Africa- the world's largest uncut diamond. Suppose the diamond's
temperature changed by 2℃ as it was cut. If the specific heat capacity of diamond is 710 J/g℃, how much energy was transferred to the diamond by the heat?
Assuming that the percentage composition is on the basis of weight percentage, therefore the mass of lithium would simply be the product of the two, that is: mass Lithium = 0.188 * 1.70 g mass Lithium = 0.3196 g = 0.32 g
