Question

what is the volume of 80.0 g of ether if the density of ether is 0.70 g/ml? o 5.6 x 10^1 o 1.1 x 10^2 o 8.8 x 10^-3 o 8.0 x 10^1

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. We need to solve for $V$, so $V = \frac{m}{
ho}$.

Step2: Substitute given values

Given $m = 80.0\ g$ and $
ho=0.70\ g/mL$. Then $V=\frac{80.0\ g}{0.70\ g/mL}\approx114.29\ mL$. In scientific - notation, $V = 1.1429\times10^{2}\ mL\approx1.1\times 10^{2}\ mL$.

Answer:

$1.1\times 10^{2}$
