Specific grabvity of 84% (w/w) pure HNO_(3) is 1.54. What volume of HN

1.	Specific grabvity of 84% (w/w) pure HNO_(3) is 1.54. What volume of HNO_(3) is required to prepare one litre of 0.5 M HNO_(3) solutions?
Answer» Solution :Specific gravity of `HNO_(3) = 1.54` `M=w/"GMM"xx1000/V rArr0.5 = x/63 xx1000/1000 rArr x = 31.5`g `31.5" g of "NHO_(3)` is present in 1 L of solution. 84 g is present in 100 g of solution 31.5 g is present in ? g of solution ` = (31.5 xx 100)/84 = 37.5` g `"Density"="WEIGHT"//"VOLUME"rArr1.54 =37.5//"volume" rArr V = 37.5//1.54= 24.35` m L `V_(1)M_(1) = V_(2)M_(2)""24.35`m L of given` NHO_(3)` is required.
