An exact number is not rounded, and cannot be changed such as placing a different item on the scale it would change.
Answer: A volume of .5650 what? And what unit will be considered?
Answer:
the energy value of the olive oil kJ/g = 36.880 KJ/g
Explanation:
we can calculate energy gained by the water which generated by the reaction from this formula :
Q = mc∆t
where:
m is the mass of water= 370 g
c specific heat of water = 4.184 J/g·°C
∆t is the change or difference in temperature in °C = 38.9 - 22.7 = 16.2 °C
by substitution:
Q = 370g * 4.184 J/g.°C* 16.2°C
= 25078.896 Joule
the energy value of the olive oil = Q / mass of olive oil
= 25078.896 Joule/ 0.68 g
=36880 J/g
= 36880 / 1000 = 36.880 KJ/g
1) Find the molar mass of sucrose: 12*12 + 22*1 + 11*16 = 342 g/mol
2) Multiply the molar mass by the number of mols: 0.185 mol * 342 g/mol = 63.27 g
