The formula of the chloride of M will be MCI2.
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
