11. For each of the following amounts, calculate the mass of the sample:
a) 5.32 mol barium iodide, Balz
b) 17.8 mol sulfur dioxide, SO2
c) 1.25 mol AspirinTM, CHO4
d) 0.234 mol magnesium nitrite, Mg(NO2)2

the answer is true.

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.
