It would be 35g because you can break the ice chunk into as many pieces as you want when you combine them back together you'll always get the same weight
Answer:
d) carbon dioxide and water
B .pure water it’s made up of oxygen and hydrogen “H2O”
The first thing we need to do here is to recognize the unit of molarity and the units of the given percentage of nitric acid.
Molarity is mol HNO3 / L of solution. This is our aim
The given percentage is 0.68 g HNO3/ g solution
multiplying this with density to convert g solution into mL solution and dividing with the molecular weight of HNO3 (63 g/mol) to convert g HNO3 to mol. Therefore we obtain
0.016 mol/ mL or 16.23 mol/ L (M)
