How many grams of NaCl are needed in order to make a liter of a 2.00 M NaCl solution? O 58.4 g O 117 g O 2.00 g​

Chemistry

vitfil [10]2 years ago

Answer:

B.) 117 g

Explanation:

(Step 1)

To find the mass, you need to first find the moles of NaCl using the molarity  ratio.

Molarity = moles / volume (L)

2.00 M = moles / 1.0 L

2.00 = moles

(Step 2)

Now that you know the moles, you can convert it to grams using the molar mass.

Molar Mass (NaCl): 22.990 g/mol + 35.453 g/mol

Molar Mass (NaCl): 58.443 g/mol

2.00 moles NaCl          58.443 g
---------------------------  x  -----------------  =  117 g NaCl
                                        1 mole

The molarity of a 4.200 L solution is 1.230 M Na2CO3. What is the mass of Na2CO3
Lerok [7]

Answer:

547.5g

Explanation:

To get the mass, you need moles.

moles = (molarity)(Liters)

moles = (1.230M)(4.200L) = 5.166 moles Na2CO3

Now, just use stoichiometry

molar mass of Na2CO3 = 2(mass of Na) + (mass of C) + 3(mass of O)

= 2(22.9) + 12.01 + 3(16) = 105.99g/mol

5.166moles(105.99g/mol)

= 547.544

But, the measurements given had 4 significant figures, so in chemistry we write:

547.5g

In this experiment you’ll be grabbing the relationship between mass and volume you’ll be placing the volume on the X axis and th
Contact [7]

The mass and volume has direct proportional to each other.

<h3>What is the relationship between mass and volume?</h3>

The volume of the object is directly proportional to its mass which means that if the volume increases the mass of the object increases also increase and vice versa. Due to this direct relationship, the line of regression will go straight between X and Y axis.

So we can conclude that mass and volume has direct proportional to each other.

The atomic mass of magnesium is the weighted average of the atomic masses of
Debora [2.8K]

Answer:

2. All the naturally occurring isotopes of Mg.

Explanation:

You want to know the atomic mass of the magnesium you use in the lab. That’s “natural” magnesium. So, you must use the weighted average of all the naturally occurring isotopes in natural Mg.

1. and 3. are <em>wrong</em>. You won’t get the correct mass for natural Mg if you use only the artificial isotopes for your calculation.

4. is <em>wrong</em>. You must use all the naturally occurring isotopes. The two most abundant isotopes of Mg account for only 90 % of the atoms. If you ignore the other 10 %, your calculation will be wrong.
