Question: How many grams are in 0.5 moles of glucose (C6H12O6)? (2023)

Options:

Correct Answer: 90 g

Solution:

Molar mass of C6H12O6 = 6*12 + 12*1 + 6*16 = 180 g/mol. Mass = 0.5 moles x 180 g/mol = 90 g.

How many grams are in 0.5 moles of glucose (C6H12O6)? (2023)

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 total mass: 6 carbon (C) atoms x 12 g/mol + 12 hydrogen (H) atoms x 1 g/mol + 6 oxygen (O) atoms x 16 g/mol.
Step 4: Perform the calculations: 6*12 = 72, 12*1 = 12, 6*16 = 96.
Step 5: Add these values together: 72 + 12 + 96 = 180 g/mol. This is the molar mass of glucose.
Step 6: To find the mass of 0.5 moles of glucose, multiply the number of moles (0.5) by the molar mass (180 g/mol).
Step 7: Perform the multiplication: 0.5 moles x 180 g/mol = 90 g.
Step 8: Conclude that there are 90 grams in 0.5 moles of glucose.
