If 44.1 g of propane react completely with 160.0 g of oxygen, 132.0 g of carbon dioxide are formed. What is the mass of the other product, water, formed in this reaction?

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

i need mutiple choices

i think   the answer is c hope i'm right

i wish i could but this one is weird give me abc and i can solve it.
