Density = mass/volume
D = 40/80 = 0.5g
D= 0.5g
C or a one of those hope it helps !!!!
Driving cars gives off gases that trap heat in the atmosphere
If the equation is complete the products would be manganese chloride and oxygen gas would be given off.
MnCl2 + O2
Answer:
V = 48.5 L
Explanation:
Converting °C to K and kPa to atm
T = 25.0°C + 273.15 = 298.15 K
P = 61.3 kPa × (1 atm / 101.325 kPa) = 0.60498 atm
Calculating the volume of gas
V = nRT / P
V = (1.20 mol)(0.082057 L•atm/mol•K)(298.15 K) / 0.60498 atm
V = 48.5 L
