Answer:
Volume of sample after droping into the ocean=0.0234L
Explanation:
As given in the question that gas is idealso we can use ideal gas equation to solve this;
Assuming that temperature is constant;
Lets 
and 
are the initial gas parameter before dropping into the ocean
and 
and 
are the final gas parameter after dropping into the ocean
according to boyle 's law pressure is inversly proportional to the volume at constant temperature.
hence,
P1=1 atm
V1=1.87L
P2=80atm
V2=?
After putting all values we get;
V2=0.0234L
Volume of sample after droping into the ocean=0.0234L
Continents are generally the largest landforms on Earth. The Eurasian continent, a combination of Europe and Asia (since they are in contact for thousands of miles along the Ural Mountains) is by far the largest landform. Even without including Europe, Asia is the largest of the individual continents.
Hope this helped.
1. If you find shielding that blocks gamma radiation,then it will most likely also block the other two types. (as the hardest radiation)
2. When nuclear radiation enters the tube of a Geiger counter, it the excited atoms of the gas contained in the tube. (this type <span>deposits all energy into a single atom)</span>
3 The particles that make up protons and neutrons and are thought to be basic units of matter are <span>quarks.</span>
Answer:
m = 0.5556 mol/kg
Explanation:
The molality of any solution is calculated using the following expression:
m = moles solute / kg solvent (1)
So in order to calculate the molality of this solution, we need to calculate the moles of the glucose using the expression:
n = mass / molecular weight (2)
The molecular weight of glucose, can be calculated using the molecular mass of the atoms in the glucose:
C = 12 g/mol; H = 1 g/mol; O = 16 g/mol
the molecular weight is:
MW = (12*6) + (12*1) + (6*16) = 180 g/mol
Then, the moles of glucose:
moles = 50 / 180 = 0.2778 moles
The solvent in this case is water, and 500 g of water is 0.5 kg of water, so the molality is:
m = 0.2778 / 0.5
m = 0.5556 mol/kg
