# How do I determine the amount of water in a sealed container to create a given pressure?

I have a sealed container with a volume of 1 liter. I want to go from an initial pressure of $p_1 = 1\text{ atm}$ and an initial temperature of $T_1=298\text{ K}$ to a final pressure of $p_2=9.95\text{ atm}$ and a final temperature of $T_2=453\text{ K}$.

I want to to use water to create the pressure. But I do not know how to determine the amount of water, how would I do that?

• How do you think you can have water at 453K which is 197 degree Celsius?Boiling point of water is 100 degree Celsius. Also, if you are going by ideal gas equation, it's applicable to gas only. So, try considering steam power. Dec 5 '16 at 1:56
• please read again my question. I put water in sealed container and then give temperature. temerature cause increasing pressure ( Antoine equation Log P= a-b/c+T, a,b,c are Antione constant). my problem is that do not know how to determine the amount of water!
