3. A leaky faucet drips at the rate of 300 mL per hour. How many liters will drip in a
ki77a [65]

Answer:

Hence , in a century<u> 0.342 liters</u> of the liquid will drip.

Explanation:

The rate of the flow of the liquid droplet is given by:

Rate=\frac{Volume}{time}

Rate=\frac{mL}{hr}

<u>Unit conversion:</u>

We need to change mL/hr into Liter/century

1 L = 1000 mL (given)

1 mL = 0.001 L......(1)

1 century = 100 year

1 year = 365 days

So, 1 century = 100 x 365 days = 36500 days

1 day = 24 hrs

So , 36500 days = 36500 x 24 hr = 876000 hr

Hence ,

1 century = 36500 days = 876000 hr

we are not asked to calculate the answer in days

1 century = 876000 hr

1 hr = 1/ 876000 century

1 hr =1.141\times 10^{-6}.....(2)

From (1) and (2) put the value in the given formula:

This is for 1 mL/hr to 1 L/century

Rate=\frac{mL}{hr}

Rate=\frac{0.001\ L}{1.141\times 10^{-6}century}

Rate=1.141\times 10^{-3}L/century

Now for 300 mL/hr . the rate will be more , multiply the answer by 300

Rate=300\times 1.141\times 10^{-3}L/century

Rate = 0.342 Liters / century

Hence , in a century 0.342 liters of the liquid will drip.

a 15.0 L tank of gas is contained at a high pressure of 8.20*10^4. The tank is opened and the gas expands into an empty chamber
Nostrana [21]

Answer:

P_2=20.5

Explanation:

Assuming that temperature is constant

According to Boyle's Law, at constant temperature pressure is inversly proportional to the volume  and mathematically it can be expressed as:

P_1V_1 = P_2V_2..........1

P_1=8.2 \times 10^4

P_2=?

V_1=15L

V_2=6.00 \times 10^4L

from the first equation after putting all the value

we get,

P_2=20.5

How many atoms are contained in 12.5 grams of silver? A. 6.97 × 1022 atoms B. 7.52 × 1024 atoms C. 0.116 atoms D. 1.92 × 10–25 a
satela [25.4K]
M(Ag)=12.5 g
Nₐ=6.022*10²³ mol⁻¹

n(Ag)=m(Ag)/M(Ag)

N=n(Ag)*Nₐ

N=Nₐm(Ag)/M(Ag)

N=6.022*10²³mol⁻¹*12.5g/107.868g/mol=6.97*10²²


A. 6.97 × 10²² atoms
