You would need 20g of glucose.
Since we want a 5% glucose solution, the mass (grams of glucose) divided by the volume (mL of the solution) should be 5% (0.05).
From the given 400mL, the equation would then be:
x g/ 400 = 0.05 g/mL
x g = (400mL)(0.05 g/mL)
x g = (400mL)(5g / 100mL)
x = 20 g
When doing problems like this, I always find it helpful to keep track of your units. They'll help guide you on what is supposed to be divided or multiplied.
