How do molecules in a solid differ from those in a liquid or gas

Chemistry

artcher [175]3 years ago

Molecules in solids are packed a lot closer together than molecules in liquids and gases, so there is far less space between solid particles. Because of this, solid particles cannot move around quickly and freely like liquids and gases, instead they only vibrate so are fairly 'locked' into the same place, so solids have fixed volume and space.

Answer:

97.0%m/m es la concentración de la solución

Explanation:

El porcentaje masa/masa (%m/m) se define como 100 veces el radio entre la masa de soluto (300g de HCl) y la masa de la solución. Para hallar la masa de la solución debemos hallar la masa del agua (Solvente) haciendo uso de la ecuación del volumen de un cono. Con el volumen del cono podemos hallar la masa del agua haciendo uso de la densidad, así:

<em>Volumen:</em>

Volumen Cono = π*r²*h / 3

Donde r es el radio = 0.300m

h la altura = 5m

Volumen = π*(5m)²*0.300m / 3

7.85m³

<em>Masa Agua:</em>

7.85m³ * (1.2g / m³) = 9.42g Agua

<em>Masa solución:</em>

300g HCl + 9.42g Agua = 309.42g Solución

<em>%m/m:</em>

300g HCl  / 309.42g * 100 =

<h3>97.0%m/m es la concentración de la solución</h3>
