6- what is the volume for 35 g of a substance with density 0.75 g/ml?

Explanation:

Step1: Recall density formula

The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass and $V$ is volume. We need to solve for $V$. Rearranging the formula gives $V = \frac{m}{\rho}$.

Step2: Substitute values

We know that $m = 35\ g$ and $\rho=0.75\ g/mL$. Substituting these values into the formula $V=\frac{m}{\rho}$, we get $V=\frac{35}{0.75}\ mL$.

Step3: Calculate the volume

$V=\frac{35}{0.75}=\frac{35}{\frac{3}{4}}=35\times\frac{4}{3}=\frac{140}{3}\approx46.67\ mL$

Answer:

$\frac{140}{3}\ mL\approx46.67\ mL$
