Webhow the problem is worded. What is the molar ratio between O3and O2? What is the molar ratio between O2and O3? Practice Problems Following each equation are two requests for molar ratios from the equation. 1) N2 + 3 H2 ---> 2 NH3 Write the molar ratios for: N2 to H2 and NH3 to H2 2) 2 SO2 + O2 ---> 2 SO3 Write the molar ratios for: WebMolar mass is the amount of mass contained within a mole amount of a certain substance. Molar mass is usually given in units of grams/mole, or g/mol. So if you have a molecule with a molar mass of 10.00 g/mol then what it's telling you is that if you gather together a moles amount of those molecules, 6.02214076 x 10^(23) molecules, then it will ...
WebThe molar mass of ammonia equals 17.04 g/mol. (c) The sum of the atomic masses for Mg(NO 3) 2 is 24.31 amu + 2(14.01 + 16.00 + 16.00 + 16.00)amu = 148.33 amu. The … WebStudents will practice calculating molar mass in a variety of ways. The front page is simple and straight forward where the back page is higher level Bloom's Taxonomy asking the students to apply molar mass in several different ways. The students have two word problems, ranking, and looking at images to then calculate the molar mass.
