PRODUCT NOTES: UREA: Urea (46 – 0 -0) is a prilled, light weight product . It can be used to make Urea solutions up to 47.82% by weight, a grade of 22 – 0 – 0 N itrogen solution. The following is a chart is various Urea solutions. From experience 23 – 0 – 0 can be produced with 160 Degree F Water.

How do I Prepare Urea Solution? | Sciencing

The word “mole” is short for a molecular weight in grams of a substance. For urea, this is 60 g per liter of solution. Make the solution in one of three ways (examples provided below): Percent-by-weight: if, for example, a 4 percent solution is desired, place the beaker on the scale and using the scoop, weigh 40 g of urea and 960 g of water.
