Answer:
n = 0.01302 moles
Explanation:
Pressure = 1.3 atm
Temperature = 31 °C + 273 = 304 K ( Converting to kelvin temperature)
Number of moles = ?
Volume = 250 mL = 0.250 L
These quantities are related by the equation below;
PV = nRT
n = PV / RT
n = (1.3 * 0.250) / (0.0821 * 304)
n = 0.01302 moles
<h3><u>Answer; </u></h3>
Energy such as heat light, are examples of non matter
<h3><u>Explanation;</u></h3>
- Matter is anything that occupies space and has weight and mass. It is also tangible, and visible.
- Not everything is matter, others such as heat and light are not matter, they are non-matter, This is because they are not tangible, they lack weight, they also lack atoms or molecules, but they are form of energy.
- Therefore, energy such as heat, and light are non matters
