Automobile batteries contain sulfuric acid. Calculate the number of grams of sulfuric acid in 0.500L of battery acid if the solution has a density of 1.28g/mL and is 38% H2SO4 (small numbers) by mass?
Can you please answer this for me?
double post.
To calculate the number of grams of sulfuric acid in 0.500L of battery acid, we need to follow these steps:
Step 1: Determine the mass of the battery acid.
Mass = Volume x Density
Given:
Volume = 0.500L
Density = 1.28g/mL
Mass = 0.500L x 1.28g/mL
= 0.64g
Step 2: Determine the mass of H2SO4 in the battery acid.
Mass of H2SO4 = Mass of battery acid x Mass % of H2SO4
Given:
Mass of battery acid = 0.64g
Mass % of H2SO4 = 38%
Mass of H2SO4 = 0.64g x 0.38
= 0.2432g
Therefore, there are 0.2432 grams of sulfuric acid (H2SO4) in 0.500L of battery acid.
