Final answer:
To find the mass of a block of ice, multiply the mass per block by the number of blocks to get 0.018 kg. For melting ice calculations, the heat transfer is set equal to the mass times the latent heat of fusion, Q = mLf.
Step-by-step explanation:
The question seeks to determine the mass of the block of ice. First, one should identify the known quantities. The mass of the ice is calculated by the provided mass per block times the number of blocks, which is 3 x 6.0 g, resulting in a total mass of 0.018 kg for the ice. The mass of soda is given as 0.25 kg. When calculating the heat transfer needed to melt the ice, the energy (Q) is set equal to the product of the mass (m) and the latent heat of fusion (Lf), using the formula Q = mLf. For example, if 1.15 × 106 J is the total heat and the latent heat of fusion for ice is 334 × 103 J/kg, solving for mass (m) would give you a mass of 3.44 kg for the ice that has absorbed that amount of heat.
