what is the change in freezing point of a 1.75 molal solution of nacl in water? the kf for water is 1.86 degrees c/m.

-6.51

Explanation:

Multiply 1.86 x 2 x 1.74 and then you get your answer.

As the molality increases by 1 m, there is a corresponding decrease of 1.86°C in the solution’s freezing point.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .
