Question

An ideal gas sample has a mass of 1.28 grams in a 0.500 L container. What is the gas's density?

a) 2.56 g/L
b) 0.64 g/L
c) 1.28 g/L
d) 0.32 g/L

Answer 1

To calculate the gas's density, divide its mass by its volume. In this case, 1.28 grams divided by 0.500 liters equals 2.56 g/L, making the correct answer a) 2.56 g/L.

Step-by-step explanation:

The density of a gas is found by dividing the mass of the gas by the volume it occupies. To calculate the gas's density, divide its mass by its volume. In this case, 1.28 grams divided by 0.500 liters equals 2.56 g/L, making the correct answer a) 2.56 g/L.

The density of the ideal gas sample can be calculated by dividing its mass, 1.28 grams, by the volume of the container, 0.500 liters. Using the formula density = mass/volume, the density is calculated as follows:

1.28 grams ÷ 0.500 liters = 2.56 g/L

Therefore, the correct answer is a) 2.56 g/L.
