If you have 3.0 liters of an unknown gas, at standard temperature and pressure conditions, then you can calculate what about that gas? mass density moles of representative particles mass and moles of representative particles

Lewis structure and molecular geometry for nh2cl

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.

Concentrations expressed as a percent by mass are useful when the solute is a a. liquid b. gas c. solid
