Question

Calculate the density in g/mL of 2.0 L of gasoline that weighs 1.29 kg . How would I do this?

Answer 1

m - mass: 1,29 kg
V - volume: 2 L
d - density: ?
______________
d = m/V
d = 1,29/2
d = 0,645 kg/L = 0,645 g/mL

Answer 2

Answer: 0.645 g/ml

Explanation:

To calculate density of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

mass of gasoline = 1.29 kg = 1290 g  $1kg=1000g$

Volume of gasoline = 2 L =2000 ml   $1L=1000mL$  

Putting values in above equation, we get:

$Density=\frac{1290g}{2000ml}=0.645g/ml$

Hence, the density of gasoline in g/ml is 0.645.
