Qual è il volume di 80.0 g di etere se la densità dell'etere è 0.70 g / mL?
Risposta:
The ether has a volume of 114 mL.
Spiegazione:
Al fine di determinare il densità, we have to use the following formula:
D=M/V
- D represents densità and it will have units of g/(mL) when talking about a liquid or units of g/(cm^3) when talking about a solid.
- M represents mass and will have units of grams g.
- V represents volume and it will have units of mL or cm^(3)
We know the mass and density, both of which have good units so all we have to do is rearrange the equation to solve for V.
V= M/D
V = (80.0cancel"g")/(0.70cancel"g"/(mL)
V =114 mL
