Answer:
Hi, even though this is really not a question or an answer to a question.
Explanation:
Do you know if any of this stuff involves 6th grade?
Answer:
= 13.0 moles O2
Explanation:
1] Given the equation: 2C8H18 + 25 O2 ----> 16CO2 + 18H2O
a. How many moles of oxygen gas are required to make 8.33 moles of carbon dioxide?
8.33 moles CO2 X
25mol O2
16mol CO2
= 13.0 moles O2
Answer:n = PV/RT = 0.923 atm x 0.250 L / (0.082057 x 290.75 K)
. n = 0.00967. mole 0.00967 mole x 6.22x10^23 molecules/mole = 6.02x10^21 molecules of gas
Explanation:
The specific gravity of the solution is 1.07, which contains 5.34g for a 5.00ml sample.
Density of a substance is
Density = Mass / Volume
= 5.34/5
= 1.07
Density of water = 1
Specific gravity = Density of substance/density of solvent
Specific gravity = 1.07 / 1
Specific gravity = 1.07
Specific gravity, often known as relative density, is the ratio of a substance's density to that of an industry standard.
If a material has a relative density that is less than 1 compared to the reference, it is less dense than the reference; if it is larger than 1, it is denser. Identical volumes of the two substances have the same mass if the relative densities are equal, or exactly 1.
