How much faster will ammonia vapor travel across a room then carbon dioxide a. 0.622
b. 1.39
c. 7.55
d. 1.61

D) 1.61 times faster

Explanation:

= √(3)RTM

R constant= 0.08206

T=constant, so in this problem we dont need a value for it

M=17.031 g/mol

√(3)(0.08206)(17.031)= 2.047

= √(3)RTM

R constant= 0.08206

T=constant, so in this problem we dont need a value for it

M= 44.01 g/mol

√(3)(0.08206)(44.01)= 3.29

Since we are trying to measure how much faster NH3 will be, we have to realize that mass and speed have an inverse relationship.

So instead of doing (2.047)/(3.29) = 6.22

we have to flip the values to get (3.29)/(2.047)= 1.61

sure what is it? ^w^

it's c. elements are placed in rows based on how may valencies electrons have.
