Sodium hydroxide<span> (</span>NaOH) in a neutralization reaction, the balanced equation for this reaction isHCl+NaOH<span>----->H(2)O + </span><span>NaC</span>
ZnO + 2HNO₃→ Zn(NO₃)₂ + H₂O
mol Zn(NO₃)₂ = mol ZnO = 0.2 (from the coefficient)
mass Zn(NO₃)₂ = 0.2 x 189 = 37.8 g (theorethical yield)
% yield = 15.3 : 37.8 x 100% = 40.48%
The volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L (option B).
<h3>How to calculate volume?</h3>
The volume of a substance can be calculated using the following formula:
P1V1 = P2V2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
153 × 3 = 304 × V2
459 = 304V2
V2 = 459/304
V2 = 1.51L
Therefore, the volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L.
