A sample of gas at 250 K has a pressure of 0.857 atm and a volume of 115 L. How many moles of gas are in the sample?
irina1246 [14]

Answer:

0.208 mol

Explanation:

Assuming the gas sample behaves like an ideal gas, we can solve this problem by using the following formula:

  • PV = nRT

Where:

  • P = 0.857 atm
  • V = 115 L
  • n = ?
  • R = 0.082 atm·L·mol⁻¹·K⁻¹
  • T = 250 K

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

  • 0.857 atm * 115 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 250 K

And <u>solve for n</u>:

  • n = 0.208 mol

dalvyx [7]
The correct option is B. 
Single replacement reaction is a type of chemical reaction, in which one element is substituted for another element in a compound. There are usually two reactants, one is a pure element and the other one is an aqueous compound. The products formed is usually made up of another pure element and a new compound. In the option B, you will notice that, in the reactant part, Mg is a pure element while in the product side, H2 is a pure element.
