Answer:
Given the balanced equation
CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)
we know that we'll get one mole CO2 for every 1 mole CH4. So let's calculate how many moles are in 50 g of CH4 by dividing it's mass by it's molar mass (16 g/mole). I get 3.125 moles. The equation says we should get the same number of moles of CO2, so set moles CO2 = 3.125 moles. Then we can find the mass of CO2 by multipying by the molar mass of CO2 (44 g/mole). We should expect 138 grams of CO2.

Hello,
In this case, since the mineral torbernite has one copper atom, two uranium atoms, twenty oxygen atoms (2x2+4x2+8), two phosphorous atoms and sixteen hydrogen atoms (12x2) and therefore forty one in total, by using the Avogadro's number one is able to compute the total number of atoms in one formula unit or one mole:
Best regards.
