Answer:
a
Explanation:
Each oxygen molecule has 2 hydrogen molecules
Answer:
Sound energy is the form of energy generated when an object vibrates. Once produced through vibrations, sound energy is transferred in waves through mediums such as air and water before it reaches your ears.
Answer:
3 molecules
Explanation: i got it right on the test, also because the 2 other ones are compounds because they have hyrdogen and oxygen attached and molecules just have particles of one element attached
The osmotic pressure π, is related to concentration i.e. molarity (M) through the following equation:
π = MRT ------(1)
where R = gas constant = 0.0821 L atm/mol-K
T = temperature (let us assume 25 C = 25 + 273 = 298 K)
M = π/RT = 0.001/0.0821 * 298 = 4.09 * 10^-5 M
Now,
molarity = moles of solute/volume of solvent in Liters
= (mass of protein/molar mass)/volume
4.09 * 10^-5 moles/L = (1.0 g/molar mass)/0.1 L
Molar mass of protein = 2.445 * 10^5 g/mole
