Step 4: Make Initial Observations
Examine the data table, which shows data for quadrat
#18.
Compare the data you recorded in Table A of your
Student Guide with Table A from quadrat #18 in the
control group. Remember that the control group
contains the quadrats without compost.
Quadrat #18
Day 1
The number of blades in your quadrat is
the number of blades in quadrat #18.
The average height of the grass in your quadrat is
the average height of the
grass in quadrat #18.
Number of Blades
Average Height (cm)

Your answer would be A for the first one and B for your second one!!

Explanation:

the same as or b and the same as or b (it's the same thing for both)

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

b is the correct answer

mark me brainliest and hope this
