A balloon with a volume of 38.2 L at 91 psi is allowed to expand into a larger can with a total volume of 77.4 L. What is the pr

adelina 88 [10]

Answer:

45 psi

Explanation:

1) Data:

a) V₁ = 38.2 liter

b) P₁ = 91 psi

c) V₂ = 77.4 liter

d) P₂ = ?

2) Formula:

According to Boyle's law, at constant temperature, the pressure and volume of a fixed amount of gas are inversely related:

PV = constant ⇒P₁V₁ = P₂V₂

3) Solution:

Solve for the unknown: P₂ = P₁V₁ /v₂

Substitute the values: V₂ = 91 psi × 38.2 liter / 77.4 liter = 44.9 9si ≈ 45 psi.

A chemist adds 135.0 mL of a 0.21M zinc nitrate (Zn(NO3) solution to a reaction flask. Calculate the mass in grams of zinc nitra

yKpoI14uk [10]

Answer:

5.36 grams the mass in grams of zinc nitrate the chemist has added to the flask.

Explanation:

$Molarity=\frac{\text{Moles of solute}}{\text{Volume of the solution (L)}}$

Moles of zinc nitrate = n

Volume of the solution = 135.0 mL = 0.1350 L

Molarity of the solution = 0.21 M

$0.21 M=\frac{n}{0.1350 L}$

$n=0.21M\times 0.1350 L=0.02835 mol$

Mass of 0.02835 moles of zinc nitrate:

0.02835 mol × 189 g/mol = 5.358 g ≈ 5.36 g

5.36 grams the mass in grams of zinc nitrate the chemist has added to the flask.
