What is the molality of a D-glucose solution prepared by dissolving 36.0 g of D-glucose, C6H12O6, in 125.9 g of water

1.59 molal

Explanation:

The definition of molality is:

So first we calculate the moles of solute (D-glucose, C₆H₁₂O₆), using its molar mass:

Then we convert grams of water into kg:

Finally we calculate the molality:

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
