Answer:
Number of moles = mass/molar mass
Explanation:
Given data:
mass of Al = 11 g
Moles = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of aluminium is 27 g/mol
Now we will put the values in formula.
Number of moles = 11 g/ 27 g/mol
Number of moles = 0.41
The number of moles in 11 g Al are 0.41 mol.
Being a producer, C)Grass, makes its own food.
<h3>Mass of CO₂ generated from the combustion : 14.277 kg</h3><h3>Further explanation</h3>
Mass Heptane : 0.348 x 17 = 5.916 kg
mass C in Heptane (MW=100.21 g/mol) :
Mass Nonane : 0.101 x 17 = 1.717 kg
mass C in Nonane (MW=128.2 g/mol) :
Mass Octane : 0.551 x 17 = 9.367 kg
mass C in Otane (MW=114.23 g/mol) :
Total mass produced :
4.959+1.446+7.872=14.277 kg
