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

Number of miles of Xe in 12.00g of Xe
Korvikt [17]
1 mol of Xe has a mass of 131 grams
x mol of Xe has a mass of 12 grams.

1/x = 131/12 Set up proportion from the information above. Cross multiply
131x = 12 Divide by 13`
x = 12/131
x = 0.0916 mol <<<< ====

Just for fun
I don't know if a calculator would even tell me the number of miles in 12 grams of Xe

The diameter is 216 * 10^-12 meters. Maybe.
1 mol of anything is 6.02 * 10^23
0.0912 mols contain x atoms

1/0.0912 = 6.02 * 10^23 / x
x = 0.0912 *  6.02 * 10^23
x = 5.49 * 10 ^ 22 This thing is going to stretch out quite a ways.

1 atom = 312 * 10^- 12 meters.
5.049 * 10^22 = x meters.
x  = 312 * 10^-12 * 5.49 * 10^22
x = 1.7 * 10 ^10 km = 1.07 * 10 ^10 miles We're talking about beyond Pluto. 

I'm sorry I should delete this. If you want to you can. Take my answer for the number of mols. It's likely correct.
