You are on an alien planet where the names for substances and the units of measures are very unfamiliar. Nonetheless, you obtain

8 quibs of a substance called skvarnick. You can trade this skvarnick for gold coins, but the vendors all measure skvarnick in units of sleps; not quibs. 13 sleps is equal to 15 quibs. If you have 8 quibs of skvarnick, how many sleps do you have? Round your answer to the nearest tenth (one decimal place). Your Answer:
Chemistry

Answer:

8 quibs of skvarnick is equal to 6.9 sleps  of skvarnick .

Explanation:

Amount of substance called skvarnick = 8 quibs

According to question ; 13 sleps = 15 quibs

So, 1 quibs = \frac{13}{15} sleps

In 8 quibs = \frac{13}{15}\times 8 sleps= 6.933\approx 6.9 sleps

8 quibs of skvarnick is equal to 6.9 sleps  of skvarnick .

What is the mass, in grams, of 7.20×1020 molecules of caffeine, c8h10n4o2?
pickupchik [31]
To determine the mass, you need to know the molecular weight of the c8h10n4o2 . The molecular weight of <span>c8h10n4o2 would be: 8*12 + 10*1 + 4*14 + 2*16= 194g/mol.
To convert the number of molecules into moles, you need to divide it with 6.02 * 10^23. The calculation of the mass of </span>c8h10n4o2 would be: 
(7.20×10^20 molecules)  /(6.02 * 10^23 molecule/mol)  * 194g/mol= 232 * 10^-3 grams= 0.232 grams

You have a sample of 75.6 g of C3H8. How many moles of C3H8 are in the sample?
dsp73

The number of moles that are contained in the given mass of propane (C_3H_8 is 1.7143 moles.

<u>Given the following data:</u>

  • Mass of propane = 75.6 grams.

<u>Scientific data:</u>

  • The molar mass of propane = 44.1 g/mol.

To calculate the number of moles that are contained in the given mass of propane (C_3H_8):

<h3>How to calculate the moles of a compound.</h3>

In this exercise, you're required to determine the number of moles of propane that are contained in the given sample:

Mathematically, the number of moles contained in a chemical compound is given by this formula:

Number\;of\;moles = \frac{mass}{molar\;mass}

Substituting the given parameters into the formula, we have;

Number\;of\;moles = \frac{75.6}{44.1}

Number of moles = 1.7143 moles.
