first find the limiting agent because this determines the amount of water produced. this is done by calculating the mole of each gas and see which has a mole that satisfy the reaction;
for hydrogen; 7.30/2 = 3.65moles
for oxygen; 7.30/32 = 0.228moles
so hydrogen is excess in amount; the required mole is 2 (according to the equation).
oxygen is less than expected so it is the limiting agent which determines the amount of water produced.
use the mole for oxygen to determine the mole of water. then find the mass by multiplying the molar mass of water with its mole.
hope that helps.
What is the largest amount of H2O in grams that can be formed when 7.30 g of H2 reacts with 7.30 g of O2, based on the balanced reaction below.
2 H2 + O2 2 H2O
