Answer:
Explanation:
Li+H2O..................LiOH+H2
mass of Li=17.8 g
No of moles of Li=17.8/7=2.5
mass of H2O=50.0 g
No of moles of H2O=50.0/18=2.8
limiting reagent is Li so 1 mole of Li produce 1 mole of LiOH therefore 2.5 mole of Li produce 2.5 moles of LiOH now we have to convert it into grams
moles=given mass/molar mass
given mass=moles*molar mass
molar mass of LiOH=24
mass=2.5*24=60 gram
Ni tengo idea,tengo novio y me rkmpio el corazon
Mass = moles x molar mass
Molar mass of eythl alcohol = 46
Mass= 0.21 x 46= 9.66g
Answer: There are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.
Explanation:
Given:
= 1.0 M,
= ?
= 0.1 M,
= 200 mL
Formula used is as follows.

Substitute values into the above formula as follows.

Thus, we can conclude that there are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.
This is a simple chemical change due to what it produces and how it is added together. Hope this helps.
