Answer : The molar mass of protein is, 
Explanation :
Formula used :
where,
= osmotic pressure = 0.138 atm
C = concentration
R = solution constant = 0.0821 L.atm/mol.K
T = temperature = 
w = mass of protein subunit = 0.155 g
M = molar mass of protein subunit = ?
V = volume of solution = 2.00 mL
Now put all the given values in the above formula, we get:
Therefore, the molar mass of protein is,
Answer:
D. Displacement and distance traveled are the same if the direction does not change.
Answer: The main difference between oxide and oxygen is that oxide is a chemical compound with at least one oxygen atom while oxygen is an element whose atomic number is 8.
Explanation: let me know if it was right or wrong
The answer is A. The vibration caused by the waves through the air eventually weaken, which is why sound diminishes easily over distance.
Answer:
By a factor of 12
Explanation:
For the reaction;
A + 2B → products
The rate law is;
rate = k[A]²[B]
As you can see, the rate is proportional to the square of the concentration of A and the of the concentration of B
.
Let's say initially, [A] = x, [B] = y
The rate law in this case is equal to;
rate1 = k. x².y
Now you double the concentration of A and triple the concentration of B.
[A] = 2x, [B] = 3y
The new rate law is given as;
rate2 = k . (2x)². (3y)
rate2 = k . 4x² . 3y
rate2 = 12 k . x² . y
Comparing rate 2 and rate 1, the ratio is given as; rate 2/ rate 1 = 12
Therefore the rate has increased by a factor of 12.
