Question

Find the mass in grams of 2.00 x 10^23 molecules of C10H15O

Answer 1

To find the mass in grams of 2.00 x 10^23 molecules of C10H15O, calculate the molar mass, convert the number of molecules to moles, and then to grams.

Step-by-step explanation:

To find the mass in grams of 2.00 x 10^23 molecules of C10H15O, we need to calculate the molar mass of C10H15O and convert the number of molecules to moles, and then to grams. The molar mass of C10H15O is calculated by adding up the atomic masses of each element in the compound. Once we have the moles of C10H15O, we can convert it to grams using the molar mass.

1. Calculate the molar mass of C10H15O:
Molar mass = (10 x atomic mass of C) + (15 x atomic mass of H) + (1 x atomic mass of O)

2. Convert the number of molecules to moles:
Moles = number of molecules / Avogadro's number

3. Convert moles to grams:
Grams = moles x molar mass

Answer 2

119.13 g C10H15O

Step-by-step explanation:

First you have to convert the molecules to moles-

2.00×10^23 molecules ( 1 mole/ 6.02×10^23 molecules)

Then convert the moles to grams (you will need a periodic table)

Looking at the periodic table, we see that C=12, H=1, and O=16

so if we add 15 O's, 10 C's and 1 H, we get 361 g.

0.33 moles ( 361 g/1 mole )= 119.13 g
