Q
Q: How many grams are in 3 moles of glucose (C6H12O6)?
Solution:
Molar mass of glucose = 6*12 + 12*1 + 6*16 = 180 g/mol. Mass = moles x molar mass = 3 moles x 180 g/mol = 540 g.
Steps: 7
Show Steps
Step 1: Identify the chemical formula of glucose, which is C6H12O6.
Step 2: Calculate the molar mass of glucose by adding the atomic masses of all the atoms in the formula.
Step 3: For glucose, calculate the mass of carbon (C): 6 atoms * 12 g/mol = 72 g.
Step 4: Calculate the mass of hydrogen (H): 12 atoms * 1 g/mol = 12 g.
Step 5: Calculate the mass of oxygen (O): 6 atoms * 16 g/mol = 96 g.
Step 6: Add the masses together: 72 g (C) + 12 g (H) + 96 g (O) = 180 g/mol.
Step 7: Use the molar mass to find the mass of 3 moles of glucose: 3 moles * 180 g/mol = 540 g.
