Table sugar is

Classify the substances shown in the table sugar in water, starch solution, salt sugar mixture and milk into A, B, C, D.

What is the molality of a solution made by dissolving 3.42 g of table sugar (sucrose, C_(12H_(22)O_(11)) in 50.0 mL of water? Strategy: Molality is the number of moles of solute dissolved per kilogram of solvent. Thus, we must find how many moles are present in 3.42 g of sucrose and how many kilograms are contained in 50.0 mL of water.

Activity 2 : Bring the active dry yeast powder from market . Take 50ml lukewarm water in a conical flask. Add 5gm of active dry yeast powder and 10 gm table sugar to that water andmix the mixture well. Keep the flask in warm place and after an hour take a drop of that mixture on a clean glass slide. Put a cover-glass on that drop and observe it under the compound microscope.

Number of atoms: How many C atoms are present in 342.3g of table sugar or surose (C_(12) H_(22) O_(11) ? Strategy : The molecule mass of surcrose is 342.3 u . Thus, its molar mass is 342.3 g. First calculate the number of moles, then calculate the number of molecules, and finally use the information that there are 12 C atoms in every molecule to find the number of C atoms. grams rarr moles of sucrose rarr molecules of surcrose rarr number of C atoms
