Hint: Solution is defined as a homogeneous mixture of solute and solvent in a relative amount that can be varied continuously until a particular limit is reached. There are three types of solutions based on the concentration of solute namely isotonic, hypotonic and hypertonic solutions.

Complete Step by step answer: The mass of solute in grams per 1ml of volume of solution is termed as Weight/Volume percentage and is denoted as w/v%.
$\dfrac{w}{v}\% = vw \times 100 \\ \\$
Where, W is the weight of solute measured in grams and V is the volume of the solution measure in ml
Volume of solution $= 1L \\$
$\Rightarrow$ Volume of solution $= 1000ml \\$
Given,
$\dfrac{w}{v}\% = 10\%$
Mass of glucose dissolved $= 1000 \times \dfrac{{10}}{{100}} \\$
$\Rightarrow$ Mass of glucose dissolved $= 100g \\$

Therefore correct answer is (3) 100g

Note: In such gravimetric analysis, we relate the weights of two substances or a weight of a substance with a volume of gas or volume of two or more gases that can be calculated by mole concept.
