COULD SOMEONE CHECK MY WORK? I WILL AWARD BRAINLIEST a solution was made by dissolving 800.0g of NaOH in 2.00L of water. With the answers given, show the work of solving the problems

Molarity answer is 10moles/L

My work: 800.0gNaOHx1molNaOH/39.118 g NaOH=20.4509434

20.4509mol NaOH/2.00L H20x 1L H2O/1kg
=10.22moles/L

Why is an elements atomic mass not listed as a whole number on the periodic table

Consider the point on the plot where 10.0 g of naoh have been added. what amount of naoh, in moles, has been added? 0.308 mol fecl3 initially present

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →
