36 grams of water vapor takes up how many liters at room temperature and pressure(293 k and 100 kpa)

The volume of gas is 48.69L.

Explanation:

To calculate the number of moles of gas, we use the equation:

Given mass of water = 36 g

Molar mass of water = 18 g/mol

Putting values in above equation, we get:

Now, to calculate the volume of gas, we use the equation given by ideal gas, which is:

where,

P = pressure of the gas = 100 kPa

V = volume of the gas = ? L

n = Number of moles of gas = 2 mol

R = Gas constant =

T = temperature of the gas = 293 K

Putting values in above equation, we get:

Hence, the volume of gas is 48.69L.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
