1) How many moles are in 4.0x10^24 atoms?
-Dominant- [34]

Answer:

<h2>6.64 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{4 \times  {10}^{24} }{6.02 \times  {10}^{23} }   \\  = 6.644518...

We have the final answer as

<h3>6.64 moles</h3>

Hope this helps you

netineya [11]

Answer:

The most recent Global Burden of

Disease (GBD) study estimates that air pollution – indoor and outdoor combined – was the cause of 5.5 million premature deaths

globally in 2013. Air pollution also has further consequences on human health, leading in particular to an increasing number of

respiratory and cardiovascular diseases. Moreover, it affects crop yields and the environment, with impacts on biodiversity and

ecosystems, amongst others. These impacts have significant economic consequences, which will affect economic growth as well as welfare

0.055 grams of PbSO4 is dissolved in 200.00 grams of H2O.
Greeley [361]

Answer:

Solution's mass = 200.055 g

[PbSO₄] = 275 ppm

Explanation:

Solute mass = 0.055 g of lead(II) sulfate

Solvent mass = 200 g of water

Solution mass = Solvent mass + Solution mass

0.055 g + 200 g = 200.055 g

ppm = μg of solute / g of solution

We convert the mass of solute from g to μg

0.055 g . 1×10⁶ μg/ 1g = 5.5×10⁴μg

5.5×10⁴μg / 200.055 g = 275 ppm

ppm can also be determined as mg of solute / kg of solution

It is important that the relation is 1×10⁻⁶

Let's verify: 0.055 g = 55 mg

200.055 g = 0.200055 kg

55 mg / 0.200055 kg = 275 ppm

An HCl solution has a concentration of 9.8 x 10-5 M. What is the pH of this solution?
Inessa05 [86]
HCl = H⁺ + Cl⁻

c(HCl)=9.8*10⁻⁵ mol/l

pH=-lg[H⁺]

[H⁺]=c(HCl)

pH=-lg{c(HCl)}

pH=-lg{9.8*10⁻⁵}=4.009

pH=4.009
