Interpretacao gerais das praticas sobre densidade de amostra solido e liquido​

Chemistry
1 answer:
Savatey [412]3 years ago
6 0

Answer:

O sólido tem densidade mais alta em comparação ao líquido.

Explicação:

A densidade da amostra sólida é maior do que a densidade do líquido porque há pouco espaço entre as partículas do sólido. A densidade tem relação inversa com o volume de uma substância, se uma substância ocupa mais espaço então sua densidade é menor, enquanto se a substância ocupa menos espaço então tem maior densidade. As substâncias sólidas ocupam menos espaço em comparação com as substâncias líquidas, então podemos dizer que a densidade do sólido é maior do que as substâncias líquidas.

You dissolve 3 moles of NaCl into 12 L of water. What is the Molarity?​
DerKrebs [107]

Molarity is moles over liter. When checking for molarity, before diving, make sure the units are correct. In this case, both units are moles and liters, so we can assume the molarity is 3/12, or 0.25 M

Please answer each thank you
liubo4ka [24]

Answer:

Properties of Metals:      

- Shiny

-Malleable

-Good Conductors of electric current

- Good conductors of heat

Properties of Non-metals:

- Dull

- Not Malleable

- Bad conductors of electric current but good electric insulators

- Poor conductors of heat

Note: The first dash for the Properties of metals goes with the first dash of Properties of Non-metals and so on.

An aqueous sodium acetate, NaC2H3O2 , solution is made by dissolving 0.395 mol NaC2H3O2 in 0.505 kg of water. Calculate the mola
liq [111]

<u>Answer:</u> The molality of NaC_2H_3O_2 solution is 0.782 m

<u>Explanation:</u>

Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg. The formula used to calculate molality:

\text{Molality of solution}=\frac{\text{Moles of solute}}{\text{Mass of solvent (in kg)}} .....(1)

Given values:

Moles of NaC_2H_3O_2 = 0.395 mol

Mass of solvent (water) = 0.505 kg

Putting values in equation 1, we get:

\text{Molality of }NaC_2H_3O_2=\frac{0.395mol}{0.505kg}\\\\\text{Molality of }NaC_2H_3O_2=0.782m

Hence, the molality of NaC_2H_3O_2 solution is 0.782 m
