What do scientists do to easily share measurements data they can understand
Stells [14]

These days, scientists all over the world use a standard system of measurements.  It's the SI or metric system.

What about scientists in the United States, Liberia, and Burma ?  These three countries are the only ones in the world that haven't adopted the metric system.  What do THEY do ?Easy.  When scientists in those countries are off work, they use the inches, yards, feet, quarts, miles and gallons that everybody around them is using.  But when they go to work, they use the same metric system that everyone else in the world is using.

A solution contains only sucrose and water. If the mole fraction of sucrose is 0.0558, determine the molality of sucrose.
lora16 [44]

Answer:

The correct solution is "3.28 m".

Explanation:

According to the question,

Mol fraction of solvent,

= 0.0558

Molar mass of water,

= 18 g/mol

Mol of H₂O in 1000 g water,

= 55.55 mol

Now,

Let the mol of solute will be "x mol".

Total mol in solution will be "55.55 + x".

As we know,

⇒ The mol fraction of solvent = \frac{x}{55.55+x}

                                        0.0558=\frac{x}{55.55+x}

                                                x=0.0558[55.55+x]

                                                x=3.09969+0.0558x

                               x-0.0558x=3.09969

                                               x=\frac{3.09969}{0.9442}

                                                  =3.38 \ m
