Answer: B
Molarity is defined as M=(m/mw)/L solution where M is molarity, m is weight, mw is molar weight and L is liters.
First we plug in the mass, which is 5, then divide by the molar weight of 39.9969 which can just be rounded to 40.
Then we convert 750mL to liters which would be 0.75 liters. The root "milli" is x10-3, therefore we convert it to become 0.75L.
Now we just solve the equation, 5/40/0.75 is 0.166 repeating decimal, or just 0.167 rounding to three significant digits.
Answer:
The function of transverse tubules is to rapidly move action potentials to the interior of the muscle fiber.
Explanation:
The function of the transverse tubules is to bring the action potential of the sarcolemmal cell membrane to the sarcomeres, where the contractile machinery of the muscle fiber is organized.
The equation for density id D=M/V, which is density is equal to mass over volume. The mass (46.8 g) divided by the volume (6 cm^3), is the density. I calculated it to be 7.8 g/cm^3
