If 100 grams of water can produce 11 grams of hydrogen gas, how many kilograms of hydrogen gas can be produced in the electrolysis of 500 kg of water?

By using the given ratio, we will find that, out of 500kg of water, we could produce 55kg of hydrogen gas.

We know that out of 100 grams of water, we can produce 11 grams of hydrogen gas.

Taking the quotient we get the ratio:

(11g/100g) = 0.11

We could conclude that for any mass of water we can produce 0.11 times that mass of hydrogen gas.

This means that if we have 500kg of water, then we can produce:

0.11*500kg = 55kg of hydrogen gas.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
