Question

cellulose = c₆h₇o₂(oh)3
how many molecules are present in the formula?
o a 7
o b 2
o c 4
o d 3
o e 1
o f 15
question 2 (1 point)
how many molecules are present in 4h₂o?
o a 15
o b 3
o c 2
o d 1
o e 4
o f 7

Explanation:

Step1: Analyze cellulose formula

The formula $\text{C}_{6}\text{H}_{7}\text{O}_{2}(\text{OH})_{3}$ represents one molecule of cellulose. There are no coefficients in front of it, so it is 1 molecule.

Step2: Analyze $4\text{H}_{2}\text{O}$ formula

The coefficient 4 in front of $\text{H}_{2}\text{O}$ indicates that there are 4 water molecules.

Answer:

Question 1: e. 1
Question 2: e. 4
