Answer:
1.1 mol
Explanation:
n=m/M, where n is moles, m is mass, and M is molar mass.
M of CO2 = 12.01+16.00+16.00 = 44.01g/mol
n=50g/44.01g/mol
n = 1.13610543 mol
n ≈ 1.1 mol
Hope that helps
Answer:
0.5077 moles
Explanation:
Data Given:
Moles = n = <u>???</u>
Temperature = T = 300 K
Pressure = P = 380 mmHg = 0.50 atm
Volume = V = 25 L
Formula Used:
Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,
P V = n R T
where; R = Universal Gas Constant = 0.082057 atm.L.mol⁻¹.K⁻¹
Solving Equation for n,
n = P V / RT
Putting Values,
n = (0.50 atm × 25 L) / (0.082057 atm.L.mol⁻¹.K⁻¹ × 300 K)
n = 0.5077 moles
Answer:
The answer is B) aluminum is a good conductor of heat.
Explanation:
For the other three choices, they all say the properties when aluminum reacts with other molecules, they are called chemical property.
Gravity
Explanation:
The unpowered cars as shown gets their potential energy from their acceleration due to gravity and the height above the ground of the hill.
Potential energy is the energy due the position or a body. It is energy primarily at rest of a body.
Potential energy = m x g x h
Where:
m = mass
g = acceleration due to gravity
h = height of the hill.
