Answer:
The total amount of Au is $ 
Explanation:
Given that,
Mass of 1.0 ml of Au
Total volume of water in oceans 
We need to calculate the volume in ml
Using given volume


We need to calculate the total mass of Au
Using given data


So, The total mass of Au is 
The mass will be in ounce,


The total amount of the Au Will be


Hence, The total amount of Au is $

Answer:
d = 70.5 mm
Explanation:
given,
length of pipe = 305 m
discharge rate = 150 gal/min
pipe diameter = ?
1 gal/min = 6.30902 × 10⁻⁵ m³/s
150 gal/min = 150 × 6.30902 × 10⁻⁵ m³/s
= 9.46 × 10⁻³ m³/s


Q = A V



f = 0.048 from moody chart using P/D = 0.00015

d = 70.5 mm
Diameter of the pipe is equal to 70.5 mm
Answer:
Concentration for the solution is 0.153 mol/L
Explanation:
Formula for the osmotic pressure is π = M . R . T . i
where M is molarity (concentration), R the universal constant for gases and T is Absolute T° (T°C + 273)
π = Osmotic pressure.
Let's replace the data given:
3.9 atm = M . 0.082L.atm/mol.K . 310K
3.9 atm / 0.082 mol.K/L.atm . 310K = 0.153 mol/L (M)
i = Van't Hoff factor (ions from the solute dissolved in solution)
In this case, we assumed no ion pairing, so i = 1
