2. What is the volume of 2.89 g of CH4 (methane gas) at STP?

use n = m / M to find the moles

once you have the moles you will be able to find the Volume wirh the formula n × Vm

Vm is always 22,4 dm³/mol

hope this helped!!

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
