How many moles of glucose are contained in 8.3 x 10^21 molecules of glucose

Chemistry
2 answers:
s2008m [1.1K]3 years ago
8 0

Answer:

So, no. of moles of glucose = 0.0138

Explanation:

No. of molecules of glucose = 8.3 \times 10^{21}

Moles is related with number of molecules as:

mol=\frac{No.\ of\ molecules}{Avogadro's\ no.}

Avogadro's no. = 6.02 \times 10^{23}

moles of formaldehyde

                =\frac{8.3\times 10^{21}}{6.02\times 10^{23}} \\=0.0138\ mol

So, no. of moles of glucose = 0.0138

How does concentration affect our daily lives in science?​
statuscvo [17]

1. <em>Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. </em>

<em>2. Physical state of the reactants and surface area.</em>

A 453 g piece of glass at 25.7∘C is left outside on a sunny day. How much heat must the glass absorb from the sun in order to re
Tju [1.3M]

Answer:

Q = 5555.6J

Explanation:

Mass of glass piece, m = 453g

initial temperature = 25.7°C

temperature to be attained = 40.3°C

⇒change in temperature, Δt = 40.3 - 25.7 = 14.6°C

specific heat of glass, s = 0.840J/g°C

Heat absorbed, Q = msΔt

⇒Q = 453×0.840×14.6 = 5555.592J

⇒<u>Q = 5555.6J</u> (rounded to the nearest tenth)

Need some help with this problem please!
Tom [10]

Answer:

18 liters

Explanation:

Step 1: Figure out what the formula and what you are dealing with.

- 25 degrees celcius is constant, so it is irrelevant for the mathmatical part.

- P1 = 1 atm

- P2 = 20 atm

- V1 = 360 liters

- V2 = trying to find

Note: remember the original equation is V1/P1 = V2/P2

- Step 2: Rearrange the equation to fit this problem, you should get...

V2 = V1 x P1 / P2

- Step 3: Fill our own numbers in. You should get...

360 L x 1 atm / 20 atm = 18 Liters (do the math)

- Answer = 18 Liters

- Remember to just follow the formula and fill it in with your own numbers.

If you need any more help comment below. I am happy to help anytime.
