Answer:
0.9726g/ml
0.9726g/cm³
Explanation:
Density is found by dividing mass by volume.
Density = mass/volume
mass = 7.1g
volume= the new level of water raised - the initial level of water
volume = 32.4 - 25.1
volume = 7.3 ml
Volume is the amount of space occupied by an object.meaning the amount of volume displaced by the object is its volume.
density = 7.1 /7.3
density = 0.9726g/ml
or 0.9726 g/cm³
If you need any clarification or more explanation pls do mention at the comment section.
hope this helps and if it does pls mark as branliest answer thx

Explanation:
The formula for calculating the enthalpy change of a reaction by using the enthalpies of formation of reactants and products is
TiCl₄(g) + 2H₂O(g) ⟶ TiO₂(s) + 4HCl(g)
ΔH°f/kJ·mol⁻¹: -763.2 -241.828 -939.7 -92.307
