According to above equation, pressure exhibited by any gas depends upon number of moles of gas, temperature and volume.
Thus, <span>pressure of a refrigerant cylinder containing saturated refrigerant is determined by temperature, number of moles of gas and volume occupied. In general, pressure exhibited by system will increase with increase in temperature and number of mole of gas, while it will decrease with increasing volume. </span>
moles of HCl used = (0.8 x 17.4) /1000= 0.0139 moles by use of reacting ratio between HCl to NH4Cl which is 1:1 therefore the moles of NH4Cl is also = 0.0139 moles molar concentration = moles /volume in liters
molar concentration is therefore= (0.0139/5) x1000 = 2.7 M
