Answer:

0.25 \frac{m^{3} }{m^{2} }

Step-by-step explanation:

Since you need to convert the cm^3 into m^3 then you start off by multiplying \frac{250,000 cm^{3} }{m^{2} } to a fraction that represents m^3 over cm^3.

Like this:

\frac{250,000 cm^{3} }{m^{2} }  ×  \frac{m^{3} }{1,000,000cm^{3} }

Because cm^3 is divided by itself in the equation you cancel them both out and then your left with:

\frac{250,000m^{3} }{1,000,000m^{2} }

And when then you divide 250,000 by 1,000,000 and you get 0.25 \frac{m^{3} }{m^{2} } which is your answer.

Please mark me as Brainliest because I worked really hard on this!

Mulch includes compost, grass clipping, leaves or other organic matter which increaese the fertility of soil by providing the necessary nutrients.

Volume of much used  = 250000 cm^3

To converting into m^3, divide it by 10^6

V = 250000 /10^6 = 0.25 m^3

Rate = 0.25 m^3 /m^2

Thus, riya is applying mulch at rate of 0.25 m^3 per m^2 of garden.

Phosphorus-32 is radioactive and has a half life of 14.3 days. Calculate the activity of a 3.5mg sample of phosphorus-32. Give y
Andreyy89

Answer:

The activity of P-32 is 3.7x10¹³ becquerels = 1.0x10³ curies.

Explanation:

The activity of P-32 can be calculated with the following equation:

A = \lambda N   (1)

Where:

N: is the number of atoms of P-32

λ: is the decay constant

We can find the number of atoms of P-32 as follows:

N = \frac{N_{A}*m}{M}  (2)

Where:

N_{A}: is the Avogadro's number = 6.022x10²³ atoms/mol

m: is the mass of P-32 = 3.5x10⁻³ g

M: is the molar mass of the radionuclide (P-32) = 32 g/mol    

Now, the decay constant is given by:

\lambda = \frac{ln(2)}{t_{1/2}}   (3)

Where:

{t_{1/2}}: is the half-life of P-32 = 14.3 days

Finally, we can find the activity of P-32 by entering equations (2) and (3) into (1):

A = \lambda N = \frac{ln(2)}{t_{1/2}}*\frac{N_{A}*m}{M} = \frac{ln(2)}{14.3 d*\frac{24 h}{1 d}*\frac{3600 s}{1 h}}*\frac{6.022 \cdot 10^{23} mol^{-1}*3.5 \cdot 10^{-3} g}{32 g/mol} = 3.7 \cdot 10^{13} dis/s      

Since a becquerel (Bq) is defined as a disintegration (dis) per second, the activity in Bq is:

A = 3.7 \cdot 10^{13} Bq

And, since a Curie (Ci) is 3.7x10¹⁰ Bq, the activity in Ci is:

A = 3.7 \cdot 10^{13} Bq*\frac{1 Ci}{3.7 \cdot 10^{10} Bq} = 1.0 \cdot 10^{3} Ci

Therefore, the activity of P-32 is 3.7x10¹³ becquerels = 1.0x10³ curies.  

               

I hope it helps you!

Answer:

first conclusion was that the whole world is made up of only 4 elements but as the time passed more elements were discovered... if the world would not contain more elements... you wouldn't be alive.

PLEASE HELP MEDALS WILL BE AWARDED!!!
ruslelena [56]

Mole percent of O2 = 10% = 0.1 moles
Mole percent of N2 = 10% = 0.1 moles
Mole percent of He = 80% = 0.8 moles
Molar Mass of O2 = (2 x 16) x 0.1 = 3.2
Molar Mass of N2 = (2 x 14) x 0.1 = 2.8
Molar Mass of He = 4 x 0.8 = 3.2
1. Molar Mass of the mixture = 3.2 + 2.8 + 3.2 = 9.2 grams
2. Since at constant volume density is proportional to mass, so the ratio of
mass will be the ratio of density.
Ratio = Molar Mass of the mixture / Molar Mass of O2 = 9.2 / 32 = 0.2875
