There are a couple of things wrong with this question.
First, as CO2 is a gas, we need to know the conditions under which the 94.6 liters was measured. If we were given the temperature and pressure at which the reaction took place, we could then calculate the number of moles of CO2 represented by that sample.
Knowing the number of moles of CO2 would allow us to determine the number of moles of H2O and then we could determine the mass. But that is the second thing wrong with this questions - what is the reaction involved? Without some chemical reaction, it would be very difficult to complete this problem.
