Well, for the atoms, one mole of anything has Avagadros number of atoms. For grams, look at the periodic table and the atomic mass is the molar mass. For the gaseous liters (O2 ,H2,and the bottom one which is STP), any mole of a gas at STP has a volume of 22.4 liters. The top one with the capital M is molarity and the equation for molarity is M=moles of thing/volume in liters. So you have the molarity which is two and the number of moles which is one. solve dor volume. So there you go.

Write the rate expression for the following reaction. H2+1/2 <br>O2 arrow H2O

julsineya [31]

Answer:

$r=-k[H_2][O_2]^{1/2}$

Explanation:

Hello!

In this case, according to the chemical reaction:

H2 + 1/2 O2 --> H2O

Since both hydrogen and oxygen are the reactants and the rate laws are written in terms of the concentration of reactants and the rate constant, we obtain:

$r=-k[H_2][O_2]^{1/2}$

Whereas the negative sign represents the consumption of those reactants and the power 1/2 the stoichiometric coefficient of oxygen in the reaction.

Best regards!
