Answer: 12 moles
Explanation: reaction C3H8+ 5 O2 ⇒ 3 CO2 + 4 H2O
1 mole propane produces 3 mol CO2. For 36 mol
Is 12 moles needed
Answer : The volume of calcium hydroxide is, 32.89 ml
Explanation :
Using neutralization law,
where,
= basicity of an acid = 1
= acidity of a base = 2
= concentration of hydrobromic acid = 0.389 M
= concentration of calcium hydroxide = 0.0887 M
= volume of hydrobromic acid = 15 ml
= volume of calcium hydroxide = ?
Now put all the given values in the above law, we get the volume of calcium hydroxide.
Therefore, the volume of calcium hydroxide is, 32.89 ml
KE=6,250Joules
You plug in your given numbers and remember to square 5 because that’s the speed
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
