WebUse a periodic table to find the molecular weight. For example to find one mole of lets say carbon-14 the equation is x/14=1 x=14grams Another example: Find 5 moles of H2O. x/18=5 x=90grams Find how many moles are in 20g. of NaCl. 20/58=x x=.345 I think you can get it from that. Add Tip Ask Question Comment Download WebNov 17, 2024 · The main equation is: moles A x (mole ratio of B/A) x molar mass of B = mass of B. The way you would use this in an actual problem is the following. You are asked how many grams of glucose are...
How do you solve STP in chemistry? - scienceoxygen.com
WebThe main idea when balancing equations is that there should be the same number of each element on both sides of the reaction. You can balance the carbons and the hydrogens first, then move onto the oxygen. The balanced equation should look like this: 2C 2 H 2 + 5O 2 → 4CO 2 + 2H 2 O Example – Using Stoichiometric Ratio (Moles) WebIf we use the Ideal Gas Law Equation PV = nRT and R=0.0821 liter-atm / mole-K, then we will have to make sure the pressure is in atm and the temperature is in Kelvin. P = 760 torr X 1 atm / 760 torr = 1 atm T = 27 + 273 = 300 K solve the Equation for V = nRT / P = (40 moles NH3) (0.0821 liter-atm / mol-K) (300 K) / 1 atm = 985.2 liters NH 3 lithonia 301 trim
