The nonvolatile, nonelectrolyte TNT (trinitrotoluene), C7H5N3O6 (227.1 g/mol), is soluble in benzene C6H6. How many grams of TNT
Alexeev081 [22]

Answer:

Explanation:

formula of osmotic pressure is as follows

p= n RT

n is mole of solute per unit volume

If m be the grams of solute needed

m gram = m / 227.1 moles

m / 227.1 moles dissolved in .279 litres

n = m / (227.1 x .279 )

= m / 63.36

substituting the values in the osmotic pressure formula

5.14 = (m / 63.36)  x .082 x 298

m / 63.36 = .21

m = 13.32 grams .

What is the main cause of increased erosion
anyanavicka [17]
The main cause of increased erosion is natural elements like rain, wind and ice. Erosion is the process by which the surface of the Earth gets worn down. 
Soil erosion is also a big thing, it is caused by mostly rain that contributes to floods. This stuff is bad for farmers because they do a lot of farming and with erosion increasing the growing crops are decreasing because of erosion.
