Answer:
Moles of carbon dioxide are 1.57
Explanation:
Using ideal gas law, you can find moles of a gas with its pressure, temperature and volume, thus:
PV = nRT
PV/RT = n
<em>Where P is pressure, V is volume (35.2L); R is gas constant (0.082atmL/molK); T is absolute temperature and n are moles</em>
At STP, temperature is 273.15K and pressure is 1atm
Replacing:
1atm×35.2L / 0.082atmL/molK×273.15K = n
<em>1.57 = n</em>
<em>Moles of carbon dioxide are 1.57</em>
Answer:
I think it's false but not sure
Answer:
0.4M NaOH
Explanation:
Molarity, M, is an unit of concentration widely used defined as the ratio between moles of solute (In this case, NaOH) and volume of solution in liters.
As the solution contains 2 moles of NaOH-Moles of solute- in 5L of solution, the molarity is:
2 moles NaOH / 5L =
<h3>0.4M NaOH</h3>
