Explanation:
Expresa los gramos de soluto por cada 100 gramos de disolución. Porcentaje masa = masa de soluto___ x 100 masa de la disolución Cuando trabajamos con la masa, podemos sumar el soluto y el disolvente para obtener la disolución.
The correct answer should be Letter B
8.3mL
Explanation:
Given parameters:
Mass of acetone = 6.54g
Density of acetone = 0.7857 g/mL
Unknown:
Volume of acetone = ?
Solution:
Density is defined as the mass per unit volume of a substance. It is expressed mathematically as shown below:
Density = ![\frac{Mass}{Volume}](https://tex.z-dn.net/?f=%5Cfrac%7BMass%7D%7BVolume%7D)
Since the unknown is volume, we make it the subject of the formula
Volume = ![\frac{mass}{density}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bdensity%7D)
Input the values;
Volume =
= 8.3mL
