See explanation.

We have:

The mass of glucose is: #m_g=0.2mul#

The mass of water is: #m_w=0.8mul#

The total mass of solution is: #m_s=m_g+m_w=1mul#

The concentration of the solution can be calculated as:

#c=m_g/m_sxx100%#

#c=m_g/(m_g+m_w)xx100%=0.2/1xx100%=20%#

Answer: The concentration is #c=20%#.
