ANSWER :
You would need 20g of glucose.
Since we want a 5% glucose solution, the
Since we want a 5% glucose solution, themass (grams of glucose) divided by the
Since we want a 5% glucose solution, themass (grams of glucose) divided by thevolume (mL of the solution) should be 5%
Since we want a 5% glucose solution, themass (grams of glucose) divided by thevolume (mL of the solution) should be 5%(0.05).
From the given 400mL, the equation
From the given 400mL, the equationwould then be:
xg/ 400 = 0.05 g/mL
xg/ 400 = 0.05 g/mLxg = (400mL)(0.05 g/mL)
xg/ 400 = 0.05 g/mLxg = (400mL)(0.05 g/mL)xg = (400mL)(5g/100mL)
xg/ 400 = 0.05 g/mLxg = (400mL)(0.05 g/mL)xg = (400mL)(5g/100mL)x= 20 g
