Calculate the density in g/mL {\rm g}/{\rm mL} of 2.0L {\rm L} of gasoline that weighs 1.29kg kg .
Express your answer to two significant figures and include the appropriate units
1.29kg/2.0L * 1000g/kg * 1L/1000mL = 0.65g/mL
To calculate the density of a substance, we need to divide its mass by its volume. Let's first convert the given volume from liters to milliliters.
1 liter = 1000 milliliters
So, 2.0 liters = 2.0 * 1000 = 2000 milliliters
Next, we divide the mass (given in kilograms) by the volume (in milliliters) to find the density:
Density = Mass / Volume
Density = 1.29 kg / 2000 mL
Now, let's do the calculation:
Density = 1.29 kg / 2000 mL
Density = 0.000645 g/mL
To express the answer to two significant figures, we round the answer to 0.00065 g/mL.
Therefore, the density of the gasoline is 0.00065 g/mL.
