What is the volume of 2.0 kg of isopropyl alcohol at 20 degrees Celsius? Density at 20 degrees is 0.785g/ml.
I got .00255 ml when using 3 sig figs.
density = mass / volume
volume = mass / density
v = 2.0E3 g / .785 g/mL = 2.5E3 mL
careful with your units
the mass is only 2 sigfig
To find the volume of 2.0 kg of isopropyl alcohol at 20 degrees Celsius, you can follow the steps below:
1. First, convert the mass from kilograms to grams:
2.0 kg = 2000 grams
2. Next, use the density formula to calculate the volume:
Density = Mass / Volume
Rearranging the formula to solve for volume:
Volume = Mass / Density
Substituting the given values:
Volume = 2000 g / 0.785 g/ml
3. Now, divide the mass by the density to find the volume:
Volume = 2547.13 ml
Since the given density has four significant figures, we will keep the final answer to the same level of precision. Therefore, the volume of 2.0 kg of isopropyl alcohol at 20 degrees Celsius is approximately 2547 ml (or 2.547 L) when rounded to four significant figures.
It seems there was an error in your calculation, yielding a volume of 0.00255 ml instead of 2547 ml. Make sure to perform the division correctly and double-check your calculations to avoid such mistakes.
