Final answer:
To determine the mass of the solid, add the mass of ice (0.018 kg) to the mass of soda (0.25 kg), resulting in a total mass of 0.268 kg.
Step-by-step explanation:
To find the mass of the solid, we can combine the known masses of the components. The mass of ice (mice) is given as 3 × 6.0 g or 0.018 kg when converted to kilograms. The mass of soda (msoda) is 0.25 kg. Adding these two masses will give us the mass of the combination:
mtotal = mice + msoda
mtotal = 0.018 kg + 0.25 kg
mtotal = 0.268 kg
Therefore, the mass of the combined solid and liquid is 0.268 kilograms.
