How many molecules are there in 2.3 grams of NH4SO2

Explanation:

First, calculate the molar mass of NH4SO2. The molar mass can determine the number of moles. Then use Avogadro's number to calculate the number of molecules.

Key Steps:

Step 1. Calculate the molar mass of your compound

Step 2. Divide 2.3 grams by the molar mass of NH4SO2, this gives us moles

Step 3. Multiply by Avogadro's number (6.02x10^23) this gives you molecules.

i think 4.44 moles

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.
