Helppp, I'm stressinggg. Brainliest and 36 points. 1) 150.0 grams of HNO3 are dissolved to make 0.500 L of solution. Find the molarity.

2) A student has 12.0 M HCI and needs to make 9.00L of 4.00 HCI. What volume of the concentrated acid is needed?

3) 40.0 grams of NaCI are dissolved to make 2.00 L of solution. Find the molarity.

4) if 50.0 mL of water are added to 250.0 mL of a 0.500 M K2SO4 solution what will the molarity of the diluted solution be?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
