Mass = molecular mass x mol
mass = 176.128 x 0.000142
mass = 0.025 g (3 s.f)
Should remain the same, the volume will decrease.
What is Solidification?
The process by which liquid metals turn into tiny solid particles at the phase boundary temperature is known as solidification or freezing.
How does solidification occur?
Solidification occurs when a liquid's temperature is reduced below its freezing point. Although the freezing point and melting point of the majority of materials are the same temperatures, this is not always the case and the words freezing point and melting point are not synonymous.
When a liquid turns into a solid, the process is always exothermic, which means heat is released.
Based on casting technology, solidification is a key component of several other processes, such as crystal growth, welding, surface alloying, the manufacturing of ingots, and the purification and refinement of raw materials. It is a crucial step in the technology of metals, as well as ceramics and polymers.

C) oxygen and D) glucose
Photosynthesis use carbon dioxide and energy from the Sun to make sugar molecules (glucose) and oxygen. Respiration use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
