Calculate the mass of 0.5 moles of Co2

And 5 moles of h20

Mass of 0.5 moles CO2 is 22 and Mass of 5 moles of H2O is 90

Explanation:

Moles =

so value of moles is given 0.5 for co2 and 5 for h2o and the molecular mass of co2 is 44 and h2o is 18 so we put these values in

Mass = Moles x Molecular Mass

and we get the answer

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
