Recrystallization Step: The procedure asks for using equal amount by mass of the crude product and the recrystallization solvent, 95% ethanol. Suppose you use 1.2g of product, how many mL of 95% ethanol would you add? Write the answer as a number (without units) with 3 significant figures (e.g. 2.15). Density of 95% ethanol = 0.86 g/mL

Respuesta :

Answer : The volume (in mL) of 95% ethanol added would be, 1.39

Explanation :

As we are given that:

Mass of 95 % ethanol = 1.2 g

Density of 95 % ethanol = 0.86 g/mL

Formula used :

[tex]\text{Volume of ethanol}=\frac{\text{Mass of ethanol}}{\text{Density of ethanol}}[/tex]

[tex]\text{Volume of ethanol}=\frac{1.2g}{0.86g/mL}[/tex]

[tex]\text{Volume of ethanol}=1.39mL[/tex]

Therefore, the volume (in mL) of 95% ethanol added would be, 1.39
