ycow [4]3 years ago
7 0

Answer:

33 g

Explanation:

Given data:

Number of moles = 5 mol

Mass of compound = 165 g

Molar mass or gram formula mass = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Now we will put the values in formula.

5 mol = 165 g/ gram formula mass

Gram formula mass = 165 g / 5 mol

Gram formula mass = 33 g/mol

How does a sample of hydrogen at 10 degrees Celsius compare to a sample of hydrogen at 350K?
Sophie [7]

Answer:

We can compare the both sample by taking into account the kinetic energy.

By increasing the temperature kinetic energy of gas molecules increased.

Explanation:

It is known that kinetic energy of molecules is increased by increasing the temperature.

We are given with two sample of hydrogen one is at 10°C and other is at 350 K.

Hydrogen sample at 10°C = 273.15 + 10 = 283.15 k

Thus one sample is at 283.15 K and other is at 350 K. So, the sample at higher temperature i.e 350 K will have more kinetic energy of molecules.

While the sample at 283.15 K will have less speed of molecule and kinetic energy.

A student conducts an experiment to determine the effect of adding salt on the boiling temperature of water. The results are sho
sineoko [7]

Answer:

The answer to your question is: The first option is correct.

Explanation:

From the data given, we conclude that as the amount of salt increases, the boiling point of water increases.

Options

If salt is added to water, the water will boil at a higher temperature This is the hypothesis for the experiment.

Salt makes water boil. This statement is not true.

If water is boiling, it must have salt added to it. This statement is incorrect, it is not the goal of the experiment.

If salt is added to water, the water will get cloudy There is not evidence of that from the information given.
