Question

85kg of NH3(g) was heated with 320kg of oxygen and HNO3 is prepared .if the final solution has volume 500L then find molarity of HNO3?​

Answer 1

Answer:

The concentration of HNO3 in the final solution is 0.182 M

Explanation:

To calculate the molarity ofthe solution aer mixing 2solutions,

we use theequation: M=→{n}1M1V1+n2M2V2V1+V2

where,n1, M and V1 are the n-factor,molarity and volume of the HNO3 n2, Mand V2 are the factor molarity and volume of the HNO3

We are given: n1=1M1=0.100MV1=40.0mLn2=1M2=0.200V2=180.00mL

Putting all the values inabove equation, we get:

M=-1×0.100×40.0)+(1×0.200×180.00)40.0+180.00M=0.182M

FINAL ANSWER- 0.182
