How many grams of water are produced when 8.25 mol hydrogen reacts with hydrogen? H2 + O2 --> H2O

148.7grams

Explanation:

We need to balance the equation first

2H2 + O2 --> 2H2O

now we set up a mole ratio where we know the mole ratio of hydrogen is 2 and the mole ratio of water is 2 as well. SInce the moles are the same, nH2O = nH2

now we can calculate mass

(m is mass of water, n is moles of water, M is molecular mass of water)

molecular mass of H2O can be found by adding atmoic mass of 2 hydrogen and one oxygen (1.01+1.01+16.00)

n = m/M rearrange to m = n*M

m = 8.25mol*18.02mol

m = 148.665g

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
