Answer : The number of moles of gas are in container 2 are 12.008 moles.
Explanation :
According to the Avogadro's Law, the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.
or,
where,
= initial volume of gas in container 1 = 1.30 L
= final volume of gas in container 1 = 2.33 L
= initial moles of gas in container 2 = 6.70 mole
= final moles of gas in container 2 = ?
Now put all the given values in the above formula, we get the final moles of the gas.
Therefore, the number of moles of gas are in container 2 are 12.008 moles.
<span> Because it is diprotic acid, we can write like R(COOH)2 ( it can be written as H2A also)
</span>R(COOH)2+2NaOH ----> R(COONa)2+2H2O
<span>25.0 ml of a 0.100 m NaOH solution
25.0 ml=0.0250 L solution Of NaOH
</span> 0.100 m NaOH=0.100 mol/L
0.0250 L *0.100 mol/L=0.00250 mol NaOH
0.00250 mol NaOH*1mol R(COOH)2/2 mol NaOH=0.00125 mol acid
0.00125 mol R(COOH)2*118g R(COOH)2/1mol R(COOH)2 = 0.148 g acid
Answer is 0.148 g <span>Succinic acid</span>
