Acetone is a three-carbon aldehyde. True/False.
stiv31 [10]

Answer: acetone is a ketone and not an aldehyde. Therefore it's false

Explanation:

Acetone is of structure CH3-CO-CH3

which makes it a ketone.

Both aldehyde and ketone have a carbonyl group but there is difference between aldehyde and ketone.

Aldehydes have a general formula R-CHO

where R is a methyl group including H atom, and CHO is the functional group.

While

Ketone have the general formula R-CO-Ri

where R and Ri are methyl groups excluding H atom, and CO is the functional group.

Hint: ketones usually end with the suffix "one" as in acetone.

A solution is prepared by dissolving 20.1 g of MgCl2 with the addition of 157.0 mL of water (density of water is 1.00g/cm3). The
Nezavi [6.7K]

Answer:

1.3 M.

Explanation:

  • We need to calculate the mass of the solution:

mass of the solution = mass of MgCl₂ + mass of water

mass of MgCl₂ = 20.1 g.

mass of water = d.V = (157.0 mL)(1.0 g/cm³) = 157.0 g.

∴ mass of the solution = mass of MgCl₂ + mass of water = 20.1 g + 157.0 g = 177.1 g.

  • Now, we can get the volume of the solution:

V of the solution = (mass of the solution)/(density of the solution) = (177.1 g)/(1.089 g/cm³) = 162.62 mL = 0.163 L.

Molarity is the no. of moles of solute dissolved in a 1.0 L of the solution.

M = (no. of moles of MgCl₂) / (Volume of the solution (L)).

<em>∴ M = (mass/molar mass)of MgCl₂ / (Volume of the solution (L)) =</em> (20.1 g/95.211 g/mol) / (0.163 L) = <em>1.29 M ≅ 1.3 M.</em>

What do chemists think is the best measurement of concentration for describing the concentration of a solid solute dissolved in
lara31 [8.8K]

Answer:

Molarity.

Explanation:

  • The molarity (M) of a solution is defined as the no. of moles of solute that dissolved in 1.0 liter of the solution.

M = (mass / molar mass) of the solute (1000 / volume of the solution).

<em>So, the best measurement of concentration for describing the concentration of a solid solute dissolved in one liter of a liquid solution is Molarity.</em>
