Question

Calculate the density in g/mL of 2.0 L of gasoline that weighs 1.34 kg

Answer 1

Density = 0.67 g/mL

Step-by-step explanation:

The density of a substance can be found by using the formula

`Density = (mass)/(volume)`

To calculate the Density in g/mL we must first convert the mass from kg to g and the volume from L to mL

For the mass

That's

1.34 kg

1kg = 1000 g

1.34 kg = 1000 × 1.34 = 1340 g

For the volume

That's

2.0 L

1 L = 1000 mL

2.0 L = 2 × 1000 = 2000 mL

So we have

mass = 1340 g

volume = 2000 mL

Substitute the values into the above formula and solve for the Density

That's

`Density = (1340)/(2000) \\ = (67)/(100)`

We have the final answer as

Density = 0.67 g/mL

Hope this helps you
