A 25.00 mL sample of sulfuric acid solution from an automobile battery reacts completely with 87.42 mL of a 1.95 M solution of potassium hydroxide. What is the molar concentration of the battery?

[H₂SO₄] = 6.82M

Explanation:

This is a sort of neutralization reaction:

A strong acid with a strong base to produce water and the correspondent salt.

H₂SO₄  +  2NaOH →  Na₂SO₄ + 2H₂O

Formula for neutralization is: M acid . volume acid = M base . volume base

M acid . 25 mL = 1.95 M . 87.42 mL

M acid = (1.95 M . 87.42 mL) / 25 mL → 6.82M

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

sure im new too!
