WebSep 3, 2024 · Molecular formulas give the kind and number of atoms of each element present in the molecular compound. In many cases, the molecular formula is the same as the empirical formula. The chemical formula will always be some integer multiple ( n) of the empirical formula (i.e. integer multiples of the subscripts of the empirical formula). WebStep 1: Calculation of total electrons present in 1 molecule of Carbon dioxide Carbon dioxide ( CO 2 ), C has atomic numbers 6 so it has 6 electrons and oxygen has atomic number 8 means it has 8 electrons. Total electrons present= 16 + 6 = 22 electrons. Step 2: Calculation of the number of electrons in one mole of carbon dioxide how many valo agents are thereWebC) 9.01 cm C) 9.01 cm mass/volume What is the volume of a 2.5 g block of metal if its density is 4.75 g/cm3? A) 0.53 cm3 B) 1.9 cm3 C) 2.5 cm3 D) 4.75 cm3 E) 11.9 cm3 mass = 2.5g D = 4.75 g/cm^3 4.75 g/cm^3 = 2.5g / V To solve for V, multiply by V on both sides and then divide by 4.75 You get V = 2.5 g / 4.75 g/cm^3 V = .526 cm^3 Section: 1.8 how many valkyries are there in god of war
