How many grams of naoh are needed to neutralize 20 ml of 0.150 m h2so4

We need 0.240 grams of NaOH

Explanation:

Step 1: Data given

Volume of a 0.150 M H2SO4 solution = 20 mL = 0.02L

Step 2: The balanced equation:

2NaOH + H2SO4 → Na2SO4 + 2H2O

Step 3: Calculate moles H2SO4

Moles H2SO4 = 0.0200 L * 0.150 M= 0.00300  moles

Step 4: Calculate moles NaOH needed

For 1 mol H2SO4 we need 2 moles of NaOH to neutralize

moles NaOH required = 0.00300 * 2 = 0.00600  moles

Step 5: Calculate mass of NaOH

Mass NaOH = 0.0600 moles * 40 g/mol

mass NaOH = 0.00600 moles * 40 g/mol = 0.240 grams

We need 0.240 grams of NaOH

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

you gotta add the following molecules so we can give u an answer
