1. What is the molecular mass of the theoretical element Antonium if 394.2 g equals 3.201 moles? 2. How many grams are present in 158 mL of a 0.5 M solution of a theoretical element named Texassium, with atomic mass of 45.7 g/mol? 3. How much water will be needed to dilute 56.0 mL a 0.5 M HCl solution to 0.3 M? 4.A chemist has performed a synthesis reaction. This reaction produced 32.2 g of product. According to the chemist's calculations, this reaction was supposed to produce 35.322 g of product. What was the chemist's percent yield? (Do not include the percent sign) 5.CH3NH2 + O2 → CO2 + H2O + N2 If 14.5 g of methylamine reacts with excess oxygen to produce 15.31 g of CO2, what is the percent yield? (Do not include the percent sign) 6. Given the below reaction, Sg + H2O → SO3 + H2S If 10.2 g of rhombic sulfur reacts with 15.3 g of water to produce 4.52 g of SO3, what is the percent yield?
