An aqueous solution of urea containing 6 g in 500 ml has a density equal to 1.05. If the molar mass of urea is 60, then the molality of the solution is :Solution in Kannada A 0.193 M B 0.190 M C 0.20 M D 0.10 M Video Solution...
Device and process for producing an aqueous solution of urea. The production device comprises: - at least one device (26) for dissolving solid urea in demineralized water, comprising a tank (42) for receiving the solid urea and the demineralized water and an outlet (62) for recovering the ...
To find the molality of the urea solution, we will follow these steps:Step 1: Calculate the weight of the solution We know the density of the solution and its volume. The formula for density is:\( \text{Density} = \frac{
The surfaces of hydrophobic graphene nanosheets (GNs) are successfully decorated, aided by urea, with FePO4-based materials in an aqueous solution. The hydrophobic GNs can easily disperse in the aqueous solution without functionalization in the presence of urea, leading to the formation of a GNs-...
