Answer:
C₅H₈O₂
Explanation:
methyl methacrylate = 100 amu
6.91g CO₂ = 0.157 moles
2.26g H₂O = 0.125 moles
0.157 ÷ 0.125 = 1.256
{(CO₂)₁.₂₅₆ + (H₂O)₁} × 4 = (CO₂)₅ + (H₂O)₄
C₅H₈O?
C₅ = 60.05 amu H₈ = 8.064 amu
60.05 + 8.064 = 68.114 amu
100 amu - 68.114 amu = 31.886 amu
O = 16 amu
O = 2
Answer:
Moles
Explanation:
Mole is used to describes the amount of matter. The one mole of every substance have different mass, because every matter has different mass. The one mole of substance is equal to the molar mass of that substance.
The molar mass of substance is the mass in gram in one mole and it is represented by g/mol.
For example:
The molar mass of oxygen is 16 g/mol. If we take 16 g of oxygen we would say we taken one mole of oxygen. If we take 32 g of oxygen than it is describe as two mole of oxygen.
Consider the following reaction:
2H₂ + O₂ → 2H₂O
In this reaction two mole of hydrogen gas combine with one mole of oxygen and produce two moles of water.
Pizza because the ingredients arent mixed together completely. you can clearly see the different ingredients as compared to the others
