Given: 2.0 mol of methanol, molar mass of methanol(32.0 g/mol)
Wanted: Grams of 2.0 mol of methanol

Grams of solute= 2.0mol * 32.0g/1 mole = x

2.0 * 32.0 = [64.0g CH3OH]

Hope this is helpful!

<h3>Answer:</h3>

                 Mass  =  64 g

<h3>Solution:</h3>

             Mole is the quantity of a substance that contains number of particles exactly equal to particles found in 12 g of Carbon-12. The number of particles are 6.022 × 10²³ also called as Avogadro Number. Mole is given as,

                         Mole =  Mass / Molar Mass    ----- (1)

Data Given;

                  Mole  =  2.0 mol

                  M.Mass  =  32.0 g.mol⁻¹

                  Mass  =  ??

Solving equation 1 for Mass,

                  Mass  =  Mole × M.Mass

Putting values,

                  Mass  =  2.0 mol × 32.0 g.mol⁻¹

                 Mass  =  64 g

Would you classify hydrogen as a metal or a non-metal? <br>Explain why.​
Igoryamba

Answer:

HYDROGEN IS A NON METAL.

HYDROGEN IS A GAS ELEMENT

Hydrogen is nonmetallic, except at extremely high pressures, and readily forms a single covalent bond with most nonmetallic elements, forming compounds such as water and nearly all organic compounds.

How many molecules are in 4.62 moles of nitric acid (HNO3)?
Lena [83]

Answer:

2.8x10^24

Explanation:

To convert moles to molecules, multiply the number of moles by Avagadro's number (6.02x10^23. Round if required.

4.62mol × 6.02x10^23 = 2.8x10^24

Two litres of an ideal gas at a pressure of 10 atm expands isothermally into a vacuum until its total volume is 10 litres. How m
nlexa [21]

Answer:

The work done and heat absorbed are both -8,1 kJ

Explanation:

The work done in an isobaric process is defined as:

W = -P (Vf - Vi)

Where P is pressure ( 10 atm)

Vf = 10 L

Vi = 2 L

Thus, <em>W = -80 atm×L ≡ -8,1 kJ</em>

This is the work done in expansion of the gas.  As the gas remains at the same temperature, there is no change in internal energy doing that all work was absorbed as heat.

I hope it helps!

pressure has little effect on the solubility of liquids and solids because they are almost incompressible. True or False
slavikrds [6]

Pressure has little effect on the solubility of liquids and solids because they are almost incompressible True.

Liquids and solids show little change in solubility with changes in pressure. As expected, gases increase in solubility with increasing pressure. Henry's Law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

External pressure has little effect on liquid and solid solubility. In contrast, the solubility of a gas increases as the partial pressure of the gas above the solution increases.

Solubility is a measure of the concentration of dissolved gas particles in a liquid and is a function of gas pressure. Increasing the gas pressure increases the number of collisions and increases the solubility, and decreasing the pressure decreases the solubility.
