If it takes three "breaths" to blow up a balloon to 1.2 l, and each breath supplies the balloon with 0.060 moles of exhaled air, how many moles of air are in a 3.0 l balloon? express your answer to two decimal places and include the appropriate units.

0.45 moles of air are in a 3.0 l balloon

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

algebraic forms separated by arithmetic operations

consists of one phrase (monomial) to many phrases (polynomial)

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

is a fixed value, can be a number

it takes three "breaths" to blow up a balloon to 1.2 l

we translate this sentence into Algebraic expressions:

3 breaths = 1.2 L

So for 3.0 l balloon will need:

3: 1.2 x 3 breaths = 7.5 breaths

Because each breath supplies the balloon with 0.060 moles of exhaled water, then for 3.0 L balloon there will be:

7.5 breaths x 0.060 = 0.45 moles
