A student collects 25 mL of gas at 0.98 bar. What volume would this gas occupy at 1.013 bar? * 3 points 25.8 mL 24.2 mL .09 mL 3
trasher [3.6K]

Answer:

24.2 mL.

Explanation:

<em>Assuming constant temperature</em>, we can solve this problem using <em>Boyle's law</em>, which states:

  • P₁V₁=P₂V₂

Where:

  • P₁ = 0.98 bar
  • V₁ = 25 mL
  • P₂ = 1.013 bar
  • V₂ = ?

We <u>input the data</u>:

  • 0.98 bar * 25 mL = 1.013 bar * V₂

And <u>solve for V₂</u>:

  • V₂ = 24.18 mL

The closest option is the second one: 24.2 mL.

Help plz. ASAP!!!!
GuDViN [60]

Answer:

Option A, 931 Kg

Explanation:

As we know that weight is equal to the product of mass and acceleration due to gravity.

Thus,

W = M * 9.8 m/s2

Substituting the given values in above equation, we get -

W = 95 * 9.8 \\W = 931Kg

Hence, option A is correct
