Step 1;write the equation for reaction
the equation for reaction is as follows
NaOH + H3PO4 ---> Na2 PO4 + H2o
then calculate the moles of H3PO4 used
that is 34.55 x1.500/1000= 0.052 moles
by use of mole ratio between NaOH to H3Po4 which is 1:1 the moles of NaOh= 0.052 moles
volume of NaOh is= moles of NaOH/ molarity
that is 0.052 /1.420=0.03662 L
in Ml = 0.03662 x1000=36.62 Ml

Answer:
250L
Explanation:
Data;
V1 = 200L
P1 = 10atm
T1 = 400K
T2 = 100K
P2 = 2atm
V2 = ?
To solve this question, we'll have to use the combined gas equation which is a combination of Boyle's law, Charles law and pressure law.
From combined gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
P1 × V1 × T2 = P2 × V2 × T1
Solve for V2,
V2 = (P1 × V1 × T2) / P2 × T1
V2 = (10 × 200 × 100) / (2 × 400)
V2 = 200,000 / 800
V2 = 250L
The final volume of the gas is 250L
