You can use this formula to solve for density--> Density= PM/ RT, where P is pressure, M is molar mass, R is the gas constant and T is temperature.
P= 1.75 atm
M= 16.01 g/ mol
R= 0.0821 atm·L/ mol·K
T=337 k
density= (1.75 x 16.01)/ (0.0821 x 337)= 1.01 g/L

Answer: The number of moles of the weak acid in the solution is 0.00396
Explanation:
To calculate the number of moles for given molarity, we use the equation:
a)
The balanced chemical reaction is:
1 mole of base uses = 1 mole of
0.00396 moles of base use =
moles of
Thus the number of moles of the weak acid in the solution is 0.00396
