4.9 moles of salt are required to be added to 1 kg water to change the boiling temperature
by 5°C.
<h3>What is the moles of Salt required to change the temperature of water by 5°C?</h3>
Based on the given equation, the molality of the solution is calculated as follows:
- Molality = change in temperature/ Kb × I
Change in temperature = 5 °C
Kb = 0.51
i = 2
Molality = 5/0.51 × 2 = 4.9 molal
Also, Molality = moles/kg of water
Moles of salt = molality × kg of water
Moles of salt = 4.9 × 1 = 4.9 moles.
Therefore, 4.9 moles of salt are required to be added to 1 kg water to change the boiling temperature
by 5°C.

Yes i think so :) hope this helped
The periodic table is organized by the atomic mass of the elements. It means if the element is in Group 2a in the periodic table, it has 2+ ions.

Here are the balanced equations
- C_2H_5OH+3O_2--->2CO_2+3H_2O+Energy
- 2AgCl-->2Ag+Cl_2
- AgNO_3+Zn--->Ag+ZnNO_3
- 3BaCl_2+Al_2(SO_4)_3--->3BaSO_4+2AlCl_3
- H_2+I_2--->2HI
