how many acres are available for farming.

How many are not available for farming?

Chemistry: How much acetic acid is in a 10-liter container of acetic acid and water that is marked 60% acetic acid?

how many liters of acetic acid are in the container.

How much is water?

Answer 1

1.

how many acres are available for farming.

Of the 38 acres, only 60% can be farmed

Acres available for farming = percent of acres that can be farmed * total acres = 60%*38 = 22.8 acres

so 22.8 acres are available for farming.

how many acres are not available for farming.

Acres not available for farming = total acres - Acres available for farming = 38 - 22.8 = 15.2 acres

so 15.2 acres are not available for farming.

2.

how many liters of acetic acid are in the container.

10-liter container of acetic acid and water that is marked 60% acetic acid

Acetic acid = percent * total volume = 60% * 10 = 6 ltr

so 6 ltr is acetic acid

How much is water?

Water = total - acetic acid = 10 - 6 = 4 ltr.

so 4 ltr of water is present.
