Answer:
Ummm a pickle is stored in glass container usually in the fridge
Explanation:
so the pickles dont go bad they go in the fridge so they dont mold. if you were to put them in a metal container they would get very cold when you put them in the fridge.
Answer:
it's the chloroplast but I'm not sure which on is it it might be the F.
Answer:

Explanation:
they would all have the same volumes
Answer:
2.5 L.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have two different values of V and P:
<em>P₁V₁ = P₂V₂
</em>
P₁ = 5.0 atm, V₁ = 3.5 L.
P₂ = 7.0 atm, V₂ = ??? L.
<em>∴ V₂ = P₁V₁/P₂ </em>= (5.0 atm)(3.5 L)/(7.0 atm) = <em>2.5 L.
</em>
Molarity is defined as the number of moles of solute per 1 L of solvent.
the mass of NaCl in the solution is 87.75 g
number of moles of NaCl is calculated by dividing mass present by molar mass
number of NaCl moles = 87.75 g / 58.44 g/mol = 1.502 mol
the number of NaCl moles in 500 mL is - 1.502 mol
therefore number of NaCl moles in 1000 mL is - 1.502 mol/ 500 mL x 1000 mL/L = 3.004 mol
molarity of NaCl is - 3.004 M
answer is D. 3.00 M
