What is the molarity of concentrated HBr solution if the acid is 48.0% by mass HBr? ( D= 1.50 g/ mL) What volume of concentrated HNO3 should be used to prepare 1.0 liter of 0.15M HNO3? Concentrated HNO3 is 70.0 % by mass HNO3 with a density of 1.42 g/mL .

Step 1
First, we need to find the moles of HBr in 1 mL of the concentrated solution. To do this, we can use the mass percentage and density given. Mass of 1 mL of solution = 1.50 g Mass of HBr in 1 mL of solution = 1.50 g * 48.0% = 0.72 g Show more…
