URGENT! I WILL GIVE BRAINLIEST Mass to Moles

Ammonium carbonate, (NH4)2CO3, is a fertilizer used to supply both nitrogen and sulfur. How many moles of ammonium carbonate are in 35.8 grams of (NH4)2CO3.

mol (NH4)2CO3

How much would the freezing point of water decrease if 4 mol of sugar were added to 1 kg of water(k=1.86 c/mol/kg for water and i=1 for sugar

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

To apply in a gold the individual gold atoms are united to each other by means of a metallic bond. how would you use the gold block to determine the atomic radius of a gold atom?
