Answer:

$n=0.78mol$

Explanation:

Hello there!

In this case, according to the given information, it possible for us to realize that this problem is solved via the ideal gas equation:

$PV=nRT$

By which we solve for n (moles) as shown below:

$n=\frac{PV}{RT}$

Then, we plug in the given pressure, volume and temperature (in K) to obtain:

$n=\frac{3.85atm*5L}{0.08206\frac{atm*L}{mol*K}*(273+27)K} \\\\n=0.78mol$

Regards!

If we increase the temperature of the reaction that occurs in plants to create sugar. What direction does the equilibrium shift.

maxonik [38]

The reaction used to produce sugar in plants is Photosynthesis,

6CO₂ + 6H₂O + heat ⇆ C₆H₁₂O₆ + 6O₂↑

we can see that this reaction is endothermic, it absorbs heat to occur

If we were to add more heat or increase the temperature, the left side of the equilibrium will be able to react much more, which would produce more glucose (aka sugar)

Hence increasing the temperature will shift the equilibrium to the right or towards the Products

Smooth muscle myosin is a motor protein that plays a crucial role in the contraction of smooth muscle. If this protein has a mol

zysi [14]

Answer: Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass, occupies 22.4 L at STP contains avogadro's number $(6.023\times 10^{23})$ of particles.

Molecular mass of protein = 480,000 g/mol

Thus 1 mole of protein weighs = 480,000 g

So 27 moles of protein weighs = $\frac{480,000}{1}\times 27=12960000g$

Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
