Sagot :
Answer:
20g of glucose
Explanation:
Since we want a 5% glucose solution, the mass (grams of gluscose) 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 = 20g
