calculate the number of grams of co2 that can be absorbed by complete reaction with a solution that contains 5.00 g of sodium hydroxide
1. Write the equation and balance it.
2. Convert 5.00 g NaOH to moles. moles = grams/molar mass.
3. Using the coefficients in the balanced equation, convert moles NaOH to moles CO2.
4. Now convert moles CO2 to grams. g CO2 = moles CO2 x molar mass CO2.

To calculate the number of grams of CO2 that can be absorbed by complete reaction with sodium hydroxide (NaOH), we need to use the balanced chemical equation for the reaction between NaOH and CO2.
The balanced equation is as follows:
2 NaOH + CO2 → Na2CO3 + H2O
From the equation, we can see that 2 moles of NaOH react with 1 mole of CO2 to produce 1 mole of Na2CO3 and 1 mole of H2O.
To start, we need to convert the mass of NaOH (5.00 g) to moles. The molar mass of NaOH is 40.00 g/mol (sodium atomic weight = 22.99 g/mol, oxygen atomic weight = 16.00 g/mol, hydrogen atomic weight = 1.01 g/mol).
Number of moles of NaOH = mass / molar mass
Number of moles of NaOH = 5.00 g / 40.00 g/mol
Number of moles of NaOH = 0.125 mol
Since the mole ratio between NaOH and CO2 is 2:1, we can determine the moles of CO2 that can react by multiplying the moles of NaOH by the mole ratio.
Number of moles of CO2 = 0.125 mol NaOH × (1 mol of CO2 / 2 mol of NaOH)
Number of moles of CO2 = 0.0625 mol CO2
Finally, to find the mass of CO2, we can use the molar mass of CO2, which is 44.01 g/mol (carbon atomic weight = 12.01 g/mol, oxygen atomic weight = 16.00 g/mol).
Mass of CO2 = number of moles of CO2 × molar mass of CO2
Mass of CO2 = 0.0625 mol × 44.01 g/mol
Mass of CO2 = 2.75 g
Therefore, approximately 2.75 grams of CO2 can be absorbed by complete reaction with 5.00 grams of sodium hydroxide.
