QuestionCalculate the number of molecules in 10.8 g of dry ice, CO.
Studdy Solution
STEP 1
Assumptions1. The given mass of dry ice is
. Dry ice is
3. We know the molar mass of is
4. Avogadro's number is molecules/mol
STEP 2
First, we need to find the number of moles of . We can do this by dividing the given mass by the molar mass.
STEP 3
Now, plug in the given values for the mass and molar mass to calculate the number of moles.
STEP 4
Calculate the number of moles of .
STEP 5
Now that we have the number of moles, we can find the number of molecules by multiplying the number of moles by Avogadro's number.
STEP 6
Plug in the values for the number of moles and Avogadro's number to calculate the number of molecules.
STEP 7
Calculate the number of molecules in of dry ice.
The number of molecules in of dry ice is molecules.
