How many moles of HCl are needed to completely react with 50.0 mL of 0.250 M NaOH solution? Group of answer choices 1.25 × 10-2
Hitman42 [59]

Answer:

n_{HCl|=1.25\times 10^{-2}\ moles

Explanation:

We know that , the reaction between NaOH and HCl is given as

HCL+NaOH\rightarrow NaCl+H_2O

Form the above reaction we can say that

Number of moles of HCl =Number of moles of NaOH

n_{HCl} =n_{NaOH}

Therefore

n_{HCl}=\frac{0.25\times 50}{1000}\ moles

n_{HCl|=12.5\times 10^{-3}\ moles

n_{HCl|=1.25\times 10^{-2}\ moles

Therefore the numbers of moles needed of HCl wil be 1.25\times 10^{-2}\ moles
