Explanation:
The density of a substance can be found by using the formula
From the question
mass of block = 5 g
volume = 15 mL
The density of the block is
We have the final answer as
<h3>0.33 g/mL</h3>
The block will float on water since it's density is less than that of water which is 1 g/mL

Answer:
universal mass unit
<h2 />
The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137 × 1023).
Endothermic because it 'sucks' the energy and that's why temperature drops
