Answer: The volume of tank is 17.5 L.

Explanation:

Given: Mass of methane = 173 g

Pressure = 15.1 atm

Temperature = 298 K

Molar mass of methane is 16.04 g/mol.

Therefore, moles of methane are calculated as follows.

No. of moles = \frac{mass}{molar mass}\\= \frac{173 g}{16.04 g/mol}\\= 10.78 mol

Now, ideal gas equation is used to calculate the volume as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

PV = nRT\\15.1 atm \times V = 10.78 mol \times 0.0821 L atm/mol K \times 298 K\\V = \frac{10.78 mol \times 0.0821 L atm/mol K \times 298 K}{15.1 atm}\\= 17.5 L

Thus, we can conclude that volume of the tank is 17.5 L.

A mixture of 0.220 moles CO, 0.350 moles H2 and 0.640 moles He has a total
emmasim [6.3K]

Answer:

P(H₂) = 0.8533 atm

Explanation:

n(CO) = 0.220 mole

n(H₂)  = 0.350 mole

n(He) = 0.640 mole

_______________

∑ n  =  1.210 moles

mole fraction => X(H₂) = 0.350/1.210 = 0.2892

Dalton's Law of Partial Pressures => P(H₂) = X(H₂)·P(ttl) = 0.2892(2.95 atm) = 0.8533 atm

Lily is trying to measure the volume of her hand. She places it in a can full of water. The volume of water that is __________ i
PolarNik [594]

Answer:

Displaced

Explanation:

A convenient way to measure the volume of an object is to measure the volume of a solid is to immerse the solid into water.

When a solid is immersed in water, it displaces some volume of water. This volume of water displaced is the same as the volume of the object.

For instance, if the volume of water in a measuring cylinder was 25 ml and i added a stone which made the water in the measuring cylinder to rise to 70 ml, it simply means that the volume of the object is 70 ml - 25 ml = 45 ml

The equation 2NaNO3 CaCl2=2NaCl Ca(NO3)2 is balanced. How many atoms of oxygen are there on each side of the equations?
morpeh [17]

Answer: There are 6 atoms on reactant side and 6 atoms on product side.

Explanation:

2NaNO_3 + CaCl_2 \rightarrow 2NaCl + Ca(NO_3)_2

As can be seen from the balanced equation the no of atoms i 1 molecule of NaNO_3 is 3, thus 2 molecules contain 6 atoms.

According to law of conservation of mass, in a balanced chemical equation the number of atoms on product side must be equal to the number of atoms on reactant side.

Thus there are 6 atoms formed in Ca(NO_3)_2.
