How many molecules of carbon dioxide (CO2) are there in 88g of carbon dioxide?
a. 1
b. 2
c. 88
d. 1.2 x 10 24
e. not enough info
The answer is D. 1.2x10^24 . I really answerede this for the nextr student. i know its waaay past when you had to turn this in
You can convert 88 g CO2 to moles. moles = grams/molar mass.
Then there are 6.022 x 10^23 molecules in one (1) mole of CO2.
1.2 *10 24
To determine how many molecules of carbon dioxide are in 88g of it, we need to use the concept of mole and Avogadro's number.
First, we need to calculate the number of moles of carbon dioxide present in 88g. The molar mass of carbon dioxide (CO2) is approximately 44g/mol. We can determine the number of moles by dividing the given mass by the molar mass:
Number of moles = Mass / Molar mass
Number of moles = 88g / 44g/mol
Number of moles = 2 moles
Next, we can use Avogadro's number to determine the number of molecules in 2 moles of carbon dioxide. Avogadro's number is approximately 6.022 x 10^23 molecules/mol.
Number of molecules = Number of moles x Avogadro's number
Number of molecules = 2 moles x 6.022 x 10^23 molecules/mol
Number of molecules = 1.2044 x 10^24 molecules
Therefore, the answer is (d) 1.2 x 10^24 molecules.
