Answer:
1. Convert the mass of A to moles dividing in molar mass
2. Convert the moles of A to moles of D (2mol A = 3mol D)
3. Convert the moles of D to mass multiplying by its molar mass
Explanation:
As you can see in the equation, 2moles of A produce 3 moles of D, the equation is:
2mol A = 3mol D
But in the problem you are having the mass of A and you need the mass of D. That means you require to convert the mass of A to moles. With the moles of A you can find the moles of D and, as last, you need to convert the moles of A to mass.
To convert mass to moles or vice versa you must use Molar Mass. That means, the answer is:
1. Convert the mass of A to moles dividing in molar mass
2. Convert the moles of A to moles of D (2mol A = 3mol D)
3. Convert the moles of D to mass multiplying by its molar mass
