Chemistry Convert the following measurement
laiz [17]

Answer:

Explanation:

8.97 x 10⁵ \frac{m}{s^2}

= 8.97 x 10² x 10⁵ \frac{cm}{s^2}

= 8.97 x 10² x 10⁵cm /(10³ms)²

= 8.97 x10 x 10⁶cm / 10⁶ ms²

= .897 x 10² \frac{cm}{ms^2}

A gas occupying a volume of 656.0 mL at a pressure of 0.884 atm is allowed to expand at constant temperature until its pressure
7nadin3 [17]

Answer:

1.14 × 10³ mL

Explanation:

Step 1: Given data

  • Initial volume of the gas (V₁): 656.0 mL
  • Initial pressure of the gas (P₁): 0.884 atm
  • Final volume of the gas (V₂): ?
  • Final pressure of the gas (P₂): 0.510 atm

Step 2: Calculate the final volume of the gas

If we assume ideal behavior, we can calculate the final volume of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 0.884 atm × 656.0 mL/0.510 atm = 1.14 × 10³ mL
