CH4 + 202 + CO2 + 2 H2O

What is the mole ratio of methane (CH4) to carbon dioxide (CO2).

1:1.

Explanation:

From the equation we see that there is one mole of methane and one mole of carbon dioxide.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
