An object has a mass of 5.003kg and a density of 2.84g/cm^3. Find its volume in
cm^3.

The answer is

Explanation:

The volume of a substance given the density and mass can be found by using the formula

From the question

Density = 2.84 g/cm³

mass = 5.003 kg

We must first convert the mass from kg to grams

If 1 kg = 1000 g

Then 5.003 kg = 5.003 × 1000 = 5003 g

Substitute the values into the above formula and solve

That's

We have the final answer as

Hope this helps you

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
