The last step is to calculate the percent by mass of each element in ammonium nitrate (nh4no3). the masses of the elements in one mole of the compound are: mass n = 28.0 g mass h = 4.0 g mass o = 48.0 g the molar mass of the compound is 80.0 g/mol. what is the mass of one mole of the compound?

Which describes fat? a: a carbohydrate that produces energy b: a nucleic acid that directs cell function c: a lipid that stores energy d: a protein that speeds up a chemical reaction

If a solution had a ph of 7 what is the solution

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
