Answer:

3.6 moles of Na

Explanation:

Reaction is this one:

2Na + Cl₂ → 2NaCl

Ratio is 2:2, so 3.6 moles of NaCl could come from 3.6 moles of Na,

If we have to convert the mass to moles

3.6 mol . 23 g/mol = 82.8 g

Answer:

3.6 moles

Explanation:

2Na + Cl2 → 2NaCl

From the balanced chemical equation above, we can tell that 2 mole of Sodium Metal reacts with 1 mole of Chlorine molecule to form 2 mole of sodium chloride.

How many moles would then form 3.6 moles of sodium chloride?

2 mol = 2 mol

x mol = 3.6 mol

Upon solving for x, we have;

x = (3.6 * 2) / 2

x = 3.6 mol

This means that 3.6 moles of sodium metal would be needed to make 3.6 moles of sodium chloride

A person suffering from hyponatremia has a sodium ion concentration in the blood of 0.116 M and a total blood volume of 4.7 L .
klemol [59]

Explanation:

Normal moles of Na^{+} = volume × normal concentration

                              = 4.7 × 0.139 = 0.6533 mol

Moles of Na^{+} in hyponatremia blood = volume × hyponatremia concentration

                              = 4.7 × 0.116 = 0.5452 mol

Moles of NaCl to be added = moles of extra Na^{+} needed

                            = 0.6533 mol - 0.5452 mol = 0.1081 mol

Mass of NaCl = moles × molar mass of NaCl

                        = 0.1081 mol × 58.443

                        = 6.317g

                        = 6.32 g (approx)

Thus, we can conclude that mass of sodium chloride would need to be added to the blood is 6.32 g.

To reduce 16 ounces of a 25% solution of antiseptic to a 10% solution, how much distilled water should a nurse add?
NemiM [27]
<span>Let x = amt of distilled water
:
A simple equation
.25(16) = .10(x+16)
4 = .10x + 1.6

4 - 1.6 = .1x
2.4 = .1x
x = 2.4/0.1
x = 24 oz of distilled water
:
:
Prove this by seeing the amt of antiseptic is the same (only the % changes)
.25(16) = .10(24+16)
4 = .1(40)

If one mole of a substance has a mass of 56.0 g, what is the mass of 11 nanomoles of the substance? Express your answer in nanog
9966 [12]

Answer:

616,0 ng is the right answer.

Explanation:

You should know that 1 mole = 1 .10^9 nanomoles

Get the rule of three.

1 .10^9 nanomoles ...................... 56.0 gr

11 nanomoles .....................

(11 x 56) / 1 .10^9 nanomoles = 6.16 x 10^-7 gr

Let's convert

6.16 x 10^-7 gr x 1 .10^9 = 616 ngr
