Question

Now sure how to do this!

1. DESCRIBE & CALCULATE how to make 750. mL of a 1.25 M sucrose solution
2. Concentrated HCl has a molarity of 12 M. DESCRIBE & CALCULATE how to make 1.50 L of a 3.00 M HCl.

Answer 1

a. 1.25M=molesSucrose/.75
moles Sucrose=1.25*.75
grams sucrose= molesSucrose*342.3
put sucrose in a beaker, add water to 750ml mark, stir, and label.

2. You want 1.50L, so in that you have 1.50*3 moles HCL, or 4.5moles
determine the volume of 12 molar in which you get 4.5moles
4.5/volume=12
volume=4.5/12 liters=375ml
so, always adding acid to water, put about 900mlof water in a beaker, add 375ml 12 molar acid slowly, stiring. When mixed, add water up to the 1.5Liter mark. label, and safely store.

Answer 2

Is 1 or part A's answer then 321

and question 2's answer is 375...??
