Given a 5.81g sample of h2 (fm =2.02), contained in a volume of 3.90l. how many atm of pressure would it have if the temperature was 64 degrees celsius?

The answer to your question is: P = 20.4 atm

Explanation:

Data

mass = 5.81 g

FM = 2.02

vol = 3.9 L

P = ?

T = 64°C = 337°K

R = 0.082 atm L / mol°K

Formula

               P = nRT / V

Process

              2.02 g  1 mol

              5.81 g  x

               x = (5.81 x 1) / 2.02

               x = 2.88 mol

             P = (2.88)(0.082)(337) / 3.9

             P = 20.4 atm

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
