Answer:
water vapor
Explanation:
because gas molecules moves the fastest
C. Ar or Argon
<span>It is the most commonly used gas between thermal window panes. Argon has 34% lower thermal conductivity than air and is therefore more suitable to be used instead of air. It is also inert and does not react or causes any form of harm.</span>
Answer:
B) we will convert the 10 g of NaCl into moles.
Explanation:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
we will convert the 10 g of NaCl into moles.
Number of moles of NaCl:
Number of moles = mass/molar mass
Number of moles = 10 g/ 58.44 gmol
Number of moles = 0.17 mol
1 Kg = 1 L
Molarity = 0.17 mol / 2 L
Molarity = 0.085 mol/L
Molarity = 0.085 M
