What volume change occurs to a 400.0 mL gas sample as the temperature increases from 22.0 °C to 30.0°C?
nasty-shy [4]
V₁ = 400.0 mL

T₁ = 22.0ºC + 273 = 295 K

V₂ = ?

T₂ = 30.0ºC + 273 = 303 K

V₁ / T₁ = V₂ / T₂

400.0 / 295 = V₂ / 303

295 x V₂ = 400.0 x 303

295 V₂ = 121200

V₂ = 121200 / 295

V₂ = 410.84 mL

hope this helps!

Suppose you are a food chemist working for a company that makes and manufactures soda. Your job is to create a new soft drink wi
Mekhanik [1.2K]

Answer:

The answer to your question is given after the questions so I just explain how to get it.

Explanation:

a)

Get the molecular weight of Phosphoric acid

        H₃PO₄ =  (3 x 1) + (31 x 1) + (16 x 4)

                    = 3 + 31 + 64

                    = 98 g

         98 g -----------------  1 mol

      0.045 g ---------------   x

          x = (0.045 x 1) / 98

          x = 0.045 / 98

          x = 0.00046 moles or 4.6 x 10 ⁻⁴

b)

Molarity = \frac{moles}{volume}

Molarity = \frac{0.00046}{0.35}

Molarity = 0.0013 or 1.31 x 10⁻³

c)

Formula            C₁V₁ = C₂V₂

                              V₁ = C₂V₂ / C₁

Substitution

                              V₁ = (0.0013)(1) / 0.01

Simplification and result

                              V₁ = 0.0013 / 0.1

                              V₁ = 0.13 l = 130 ml

There are so many routes by which water can move through the various stages in the water cycle.

<h3>What is the water cycle?</h3>

The water cycle has to do with the route of movement of water in the enviroment. We have to note that there are so many routes by which water can move through the various stages in the water cycle.

The sun supplies the energy that drives the water cycle. This is seen in the fact that the supply of energy from the sun is required for evaporation to take place.
