Molarity of a solution is the molar concentration, which is the number of moles of solute in 1 L of solution.
the mass of glucose is - 125 g
number of moles of glucose - 125 g / 180.16 g/mol = 0.694 mol
the number of moles of glucose in 650.0 x 10⁻³ L - 0.694 mol
number of moles of glucose in 1 L - 0.694 mol / 650.0 x 10⁻³ L = 1.068 mol/L
molarity of glucose solution is 1.068 M
Answer:
i think b is the answer hope this helps:))
Answer:
A hydrocarbon and oxygen
Explanation:
hydrocarbon is being burned, and oxygen is necessary to burn things
D. layer B is younger than layer G.
This one is easy. It's just addition and subtraction. Add the partial pressure of Argon and the partial pressure of Helium:
152 kPa
<u>+305 kPa</u><u>
</u> 457 kPa
Next, subtract the result from the total pressure:
1015 kPa
<u>- 457 kPa</u>
558 kPa
