15 a flask weighs 345.8 g. with 225 ml of carbon tetrachloride, it weighs 703.55 g. calculate the density of carbon tetrachloride. a 1.20 g/ml b 1.59 g/ml c 1.40 g/ml d 1.50 g/ml

Answer

Explanation:

Step1: Find mass of carbon - tetrachloride

Mass of carbon - tetrachloride = Total mass - Mass of flask. So, $m=703.55\ g - 345.8\ g=357.75\ g$.

Step2: Calculate density

Density formula is $\rho=\frac{m}{V}$. Given $V = 225\ mL$ and $m = 357.75\ g$. Then $\rho=\frac{357.75\ g}{225\ mL}=1.59\ g/mL$.

Answer:

B. 1.59 g/mL
