Question

What mass of glucose dissolved in 100 g of 20% (M/M)glucose solution in water at constant temperature?​

Answer 1

please mark me brilliance

Answer 2

Given:

Mass percentage = 20%

Mass or weight of the mixture or solution =  100 gram

To Find:

Mass or weight of glucose = ?

Solution:

We calculate the value of mass of glucose by this formula

Mass- percentage is the mass or weight of solute divided by total mixture or solution weight ( mass or weight of solute plus weight or mass of solvent) multiply by 100

Mass percentage help in determining or measuring concentration of one element in the total mixture

$Mass (in percentage) = \dfrac{solute Mass}{ solution mass} 100$

$20 = \dfrac{ x}{ 100} 100$

$x = 20 gm$

20 gram mass of glucose is dissolved in total 100 gram of mixture
