Answer:
Average acceleration = - 2 m/s^2
Explanation: Have a nice day
1 mole of any gas under STP has volume 22.4 L,
we have 2 mole of gas, so volume of container should be 2*22.4 L= 44.8 L
Explanation:
Equation of the reaction:
H2X(aq) + 2NaOH(aq) --> Na2X + 2H2O
Mass of acid = 0.178 g
Number of moles = molar concentration * volume
= 0.095 * 25.20 mL⋅1 L/1000 mL
= 0.00239 mol
From the equation of reaction,
2 moles of NaOH neutralises in 1 mole of H2X.
Therefore,
0.00239 mole of NaOH, number of koles of H2X = 2 * 0.00239 mol
= 0.0012 mole.
Molar mass = mass/number of moles
= 0.178/0.0012
= 148.7 g/mol.
