What is the molality of a solution made by combining 5.0 g of CaCl2 with 500.0 g of water?
ankoles [38]
Molality is defined as the number of moles of solute dissolved in 1 kg of solvent.
To calculate molality, we need to calculate the number of moles of CaCl₂.
Mass of CaCl₂ - 5.0 g
Molar mass of CaCl₂ - 111 g/mol
The number of moles of CaCl₂ - 5.0 g / 111 g/mol = 0.045 mol 
we need to then calculate the number of moles in 1 kg solvent.
number of CaCl₂ moles in 500 g water - 0.045 mol
Therefore number of moles in 1 kg water - 0.045 mol / 500g x 1000 g = 0.090 mol
Molality of CaCl₂ - 0.090 mol/kg

¿Cuál es la densidad en g / mL de un material, si 30mL tienen una masa de 6 Kg?
blsea [12.9K]
Hola!

La densidad es una magnitud intensiva, es decir, no depende de la cantidad de material. La densidad se define como la relación entre la masa y el volumen de un cierto material y comúnmente se expresa en g/mL. A partir de esta definición podemos concluir que para hallar la densidad de un material es necesario conocer su masa y su volumen para posteriormente aplicar la ecuación tal como se describe a continuación:

densidad= \frac{masa}{volumen}= \frac{6 kg}{30mL}* \frac{1000g}{1kg}=200g/mL

Entonces, la opción correcta es la C. 200 g/mL

Saludos!

74. Is the charge of a nucleus positive, negative, or zero?<br> The charge of an atom?<br> J
tia_tia [17]
The charge of a nucleus is neutral, meaning it’s zero

the positive charges of an atom equal the negative charges so the atom has a neutral charge
