I am Not Sure About Your Question But,
Although every person's daily caloric intake is individual, based on their personal goals and needs, nutrition experts estimate that average daily consumption at each meal should be broken down as follows: 300 to 400 calories for breakfast, and 500 to 700 calories each for lunch and dinner.
Water requires 40.65 kJ of heat per mole to vaporize it completely
Multiply this by the number of moles you have
40.65 kJ x 3.3 moles = 134.145 kJ

Answer:
2.33×10¯¹⁶ g of forsterite
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms. This equally means that 1 mole of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
1 mole of forsterite (Mg2SiO4) = (24×2) + 28 + (16×4)
= 48 + 28 + 64
= 140 g
Finally, we shall determine the mass of forsterite that contains a million oxygen atoms.
140 g of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
Therefore, Xg of forsterite (Mg2SiO4) will contain 1×10⁶ atoms of oxygen i.e
Xg of forsterite (Mg2SiO4) =
(140 × 1×10⁶) /6.02×10²³
= 2.33×10¯¹⁶ g
Therefore, 2.33×10¯¹⁶ g of forsterite contains a million oxygen atoms..
