Answer: 8 feet

Explanation:

1) The diameter and the area of a circle are related by this formula:

Area = π (radius)^2 = π (diameter / 2) ^2 = π (diameter)^2 / 4

2) Since you know the area you can find the formula for the diameter:

(diameter)^2 = 4 * area / π

=> diamter = √ [4*area / π]

3) Replace the value of the area

area = 16π (feet)^2

=> diameter = √ [ 4 * 16 π (feet)^2 / π ] = √ 64 feet = 8 feet

Answer: diameter = 8 feet

Gas is heated from 480. K to 750. K and the pressure is kept constant, what final volume would result if the original volume was
attashe74 [19]
Charles law gives the relationship between volume and temperature of gas.
It states that at constant pressure volume is directly proportional to temperature
Therefore
V/ T = k
Where V - volume T - temperature in kelvin and k - constant
V1/T1 = V2/T2
Parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
Substituting the values in the equation
267 L/ 480 K = V / 750 K
V = 417 L
Final volume is 417 L

What is the mass of 5 moles of Fe2(CO3)3 ?
sineoko [7]

Answer:

1218.585

Explanation:

Looking at the subscripts we know there are 2 atoms of Fe, 3 atoms of C, and 6 of O.

Take the molar mass of each atom (from the periodic table) and multiply by the # of atoms

Fe: 55.845×2= 111.69

C: 12.011×3= 36.033

O:15.999×6=95.994

Add the values together: 243.717 g/mol

That is 1 mole of the molecule. Multiply by 5 for the final answer.

243.717×5=1218.585
