A chemical procedure calls for 3.54mol of dry ice (solid CO2). What mass of CO2 should we add?
g = mols x molar mass
Please!! Explain
1 mol CO2 = 44 grams.
3.54 mol = 3.54 x 44 = ?g
What's to explain?
To find the mass of CO2 needed, we can use the molar mass of CO2 and the given number of moles.
The molar mass of CO2 can be found by adding the atomic masses of carbon (C) and oxygen (O). The atomic mass of carbon is approximately 12.01 g/mol, and oxygen is approximately 16.00 g/mol. Therefore, the molar mass of CO2 is:
Molar mass of CO2 = (12.01 g/mol) + 2 * (16.00 g/mol) = 44.01 g/mol.
Now, we can calculate the mass of CO2 by multiplying the number of moles by the molar mass:
Mass of CO2 = Number of moles * Molar mass of CO2.
Substituting the given number of moles (3.54 mol) into the equation, we have:
Mass of CO2 = 3.54 mol * 44.01 g/mol.
Calculating this expression gives:
Mass of CO2 = 155.8754 g.
Therefore, you should add approximately 155.88 grams of CO2 to the chemical procedure.
