What is the molarity of a solution made with 87g of Mgo dissolved in enough water to make
JulsSmile [24]

Answer:

2.70 M.  

Explanation:

Molar mass of MgO = 24.3 + 16 = 40.3.

A molar solution will contain 40.3g in 1 Litre.

So 800 mL of 1 molar solution will contain 0.8* 40.3 g MgO.

So the molarity of the given solution

= 87 / (0.8*40.3)

= 2.699 M.

How many moles of carbon atoms is 7.72 x 10 ^24 atoms of carbon? Round to 2 decimal places
soldier1979 [14.2K]

Answer:

<h2>12.82 moles </h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{7.72  \times {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 12.8 239

We have the final answer as

<h3>12.82 moles</h3>

Hope this helps you
