What is the molality of a solution containing 100 grams of glucose (C6H12O6, molar mass = 180 g/mol) dissolved in 2.5 kg of water?

Group of answer choices

40 m

0.22 m

72 m

7200 m

The answer to your question is molality = 0.22

Explanation:

Data

molality = ?

mass of glucose = 100 g

molar mass of glucose = 180 g

mass of water = 2.5 kg

Process

1.- Calculate the moles of glucose using proportions

                180 g 1 mol

                100 g  x

                   x = (100 x 1) / 180

                   x = 100 / 180

                   x = 0.56 moles

2.- Calculate the molality

Formula

molality = moles / mass of solvent

- Substitution

molality = 0.56 / 2.5

- Simplification

molality = 0.22

they are both synthetic elements

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
