Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams
Answer:
Smooth muscle fibers have an oblong shape, much like a football. They’re also thousands of times shorter than skeletal muscle fibers. Similar to skeletal muscles, cardiac muscles are striated. They’re only found in the heart. Cardiac muscle fibers have some unique features.
Explanation:
I believe the answer is decomposition. please let me know if that is correct.
Answer:
ABC transporter protein
Explanation:
ABC transporter protein refers to the ATP binding cassette protein which utilizes the AT energy to transport the substrates from one side to another side. The ABC proteins are one of the oldest proteins known in the organisms.
The CFTR protein which acts as a chloride channel in the membrane which transports the chloride ions across the membrane utilizes the ATP energy in the transport.
Thus, ABC transporter protein is correct
