a 2.00-liter sample of a gas has a mass of 1.80 grams at STP. What is the density , in grams per liter , of this gas at Stp?
Why not g/L? Just 1.80g/2.00L - ?
To find the density of a gas at STP (Standard Temperature and Pressure), we need to know its mass and volume. In this case, we are given the mass as 1.80 grams and the volume as 2.00 liters.
The formula to calculate density is:
Density = Mass / Volume
Substituting the given values:
Density = 1.80 grams / 2.00 liters
Now, performing the division:
Density = 0.90 grams per liter
Therefore, the density of the gas at STP is 0.90 grams per liter.
