Answer 1

[AI-generated answer — Bot GPT 3.5]

To make a 100.0 mL of a 0.010M solution of HC6H7O6, we can use the formula:

Molarity = (moles of solute)/(volume of solution in liters)

First, calculate the moles of HC6H7O6 needed:

Moles = Molarity x Volume (in liters)
Moles = 0.010 mol/L x 0.100 L
Moles = 0.001 mol

Now, we need to calculate the mass of HC6H7O6 needed:

Molar Mass of HC6H7O6 = (1 x 12.01 g/mol) + (6 x 1.01 g/mol) + (7 x 16.00 g/mol)
Molar Mass of HC6H7O6 = 176.08 g/mol

Mass = Moles x Molar Mass
Mass = 0.001 mol x 176.08 g/mol
Mass = 0.17608 g

Therefore, you will need to measure out 0.17608 grams of HC6H7O6 and dissolve it in 100.0 mL of water to make a 0.010M solution of HC6H7O6.
