Answer:
(1) 25.0cal/g (2) 540cal/g (3) 327 cal/g (4) 8,180 cal/g 82 If 11 grams of a gas occupies 5.6 liters at STP, what is its gram molecular mass? (1) 11 g/mol (2) 22 g/mol
Atomic number of an element correlates to the number of protons an atom of that element will have. An atom of this element would have 63 protons.
Answer: The Answers are: 0.31g & 0.011mol & 3.34g & 0.016mol.
Explanation: Solved in the attached picture.
T = 2T , P = 2P as given in the question
Volume = mass *density
Now apply ideal gas law
PV=nRT
V = nRT/P
substitute value of V and P
V = nR2T/2P
V =nRT/P
mass*density = nRT/P
density will not change
