A calculator was purchased for $29. The wholesale cost was $20. What was the percent markup?
Oxana [17]
If you would like to find the percent markup, you can calculate this using the following steps:

x% of $20 is $29
x% * 20 = 29
x/100 * 20 = 29
x = 29 * 100 / 20
x = 145%

145% - 100% = 45%

The correct result would be 45%.

The molar mass of AlCl3 is 133.34 g/mol. How many molecules of AlCl3 are there in 2 g?
Mnenie [13.5K]

To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3.  2g of AlCl3 contains 9.034*10^21 molecules.

<h3>Number of Molecules in 2g of AlCl3</h3>

The molar mass of AlCl3 is given as 133.34g/mol

Data;

  • mass = 2g
  • molar mass = 133.34g/mol

Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.

133.34g = 6.023*10^2^3

If we equate this

133.34g = 6.023*10^2^3\\2g = x molecules\\x = \frac{2*6.023*10^2^3}{133.34} \\x = 9.034*10^2^1 molecules

From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.

Please help<br><br><br> hggggggggggh
Luba_88 [7]

Answer:

The first blank is: 26

The second blank is: 17

The third blank is: 31 - n

Step-by-step explanation:

So basically each row should add up to 31.  So for every number they give you (doesn't matter which color ball), you need to subtract it from 31.

That's why for the first blank, 31 - 5 is 26

second blank, 31 - 14 is 17

and so on....

so the resulting function would be 31 - n

n being a random number that is given to you
