Answer:

The current loss figure is equivalent to ~25,920 liters per day or 9,467 m3 per year

It isn't a percentage, but I hope that helps a little

Calculate the compound amount. Use the compound amount formula and a calculator. (Round your answer to two decimal places.) P =

Julli [10]

Answer:

The compound amount is $303.03 .

Explanation:

Formula for compound interest:

$A=P\times (1+\frac{R}{n})^{tn})$

Principle amount = $1100

Rate of the interest compounded semiannually :

= R = 9% = 0.09

Number of times interest compounded, n = $\frac{12}{6}=2$

(semi means two times in a year)

Time period = T = 14

$A=\$1100\times (1+\frac{0.09}{2})^{2\times 14}=\$303.0310\approx \$303.03$

The compound amount is $303.03 .

To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 3.6-L bulb, then filled

aleksandrvk [35]

Answer:

The gas was N₂

Explanation:

V = 3.6L

P = 2.0 atm

T = 24.0°C = 297K

R = 0.0821 L.atm/K.mol

m = 8.3g

M = molar mass = ?

Using ideal gas equation;

PV = nRT

n = no. Of moles = mass / molar mass

n = m/M

PV = m/M * RT

M = mRT / PV

M = (8.3*0.0821*297) / (2.0*3.6)

M = 28.10

Since X is a diatomic molecule

M = 28.10 / 2 = 14.05 g/mol

M = Nitrogen

X = N₂
