How to solve 5gNaCl= MolE NaCl
valentinak56 [21]

0.086mole

Explanation:

The problem is very simple. It involves conversion from mass to number of moles of NaCl

What is mole?

 A mole is a unit of measuring chemical substances. It is the amount that contains the avogadro's number of particles.

How is it related and can be converted from mass;

 

Number of moles of a substance = \frac{mass}{molar mass}

Since we know the mass, we can find the molar mass and put into this equation;

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Number of moles of NaCl = \frac{5}{58.5}  = 0.086mole

nexus9112 [7]

Answer:

1. 374.69 K

Explanation:

Hello,

In this case, pure water's boiling point is 373.15 K, thus by considering the boiling point increase equation:

\Delta T=imKf

Whereas i=2 since two ionic species are formed,actually, the experimental value is 2.42 so better work with it, thus:

\Delta T=2.42*(\frac{8}{8}m)*0.512 Km^{-1}=1.239K

Thus, the required boiling point is:

T_b=373.15K+1.239K\\T_b=374.69K

Regards.
