mass percent of nitric acid being 69% means 69 grams of nitric acid present in 100 grams of water.so we got weight of nitric acid.density of solution is given to be 1.41 g/ml.so using density =mass/volume Find the volume of nitric acid.so now we have weight and volume.calculate the concentration using the formula M=weight /molecular weight*1000/volume.
