What is the mass of H2o required to dissolve 14.5g of glucose if the molality of solution is 0.24 molal

Mass of water = 0.33 Kg

Explanation:

Given data:

Mass of water = ?

Mass of glucose = 14.5 g

molality of solution = 0.24 m

Solution:

Number of moles of glucose:

Number of moles = mass/molar mass

Number of moles = 14.5 g/ 180.156 g/mol

Number of moles = 0.08 mol

Mass of water:

Molality = number of moles of solute / Kg of solvent

0.24 m = 0.08 mol / Kg of solvent

Kg of solvent =  0.08 mol / 0.24 m

Kg of solvent = 0.33 Kg

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
