The balanced chemical equation for the combustion of butane is: 2C₄H₁₀ + 13O₂ -> 8CO₂ + 10H₂O. This means it requires 13 moles of O₂ for every 2 moles of butane. The volume of O₂ needed would be (14.9 L * 13 mol) / 2 = 96.85 L of O₂.
The freezing point of a solution can be calculated using the formula: ΔTf = i * Kf * m, where ΔTf is the freezing point depression, i is the Van't Hoff factor (for complete dissociation i = number of ions after dissociation), Kf is the cryoscopic constant, and m is the molality of the solution.
To determine the atom radius of gold, you can measure the volume of the gold block and then calculate the number of atoms in the block using Avogadro's number and the molar mass of gold. From there, you can calculate the radius by assuming the gold atoms are arranged in a cubic or face-centered cubic structure within the block.
It can take approximately 3-7 days for THC to be cleared from the system of someone who weighs less than 100 pounds, assuming normal metabolism and hydration levels. However, factors like frequency of use, metabolism, and individual body chemistry can influence how long THC remains detectable.
When allowed to stand for long enough, the final temperature will reach room temperature.
Assuming you know the circumference (C) it's... (C/Pi)/2.
Assuming you know the radius - the formula is Pi x Radius2
Assuming the room is rectangular, multiply length x width (both in feet).
Assuming you mean to convert it to degrees Fahrenheit - multiply the 23 by 1.8, then add 32 to get the answer 73.4
Assuming interest is compounded annually, 1000*(1.08)5
Knowing the total area is not enough. You need to know the occupancy proportion as well.
Assuming that "r" is the radius, that simply isn't sufficient information to calculate angular velocity.
Assuming I've understood what you're trying to ask: first calculate the mass, then convert that to a volume using the density.
Not sure I understand the question, assuming it's in the right section. "Solve" is not an abbreviation or acronym in mathematics, but the verb meaning "calculate" or "find the answer to".
(assuming its a cylinder) volume = pi * radius2 * height so: radius = square root ( volume / ( pi * height ) )
Nothing, I'm fairly sure you just invented the word 'matabalism'. assuming you meant metabolism: These are all factors which impact your metabolism -weight -how active the person is -how much of the person's mass is muscle -age -sex -diet -genes
Assuming it is spherical: area = 4 x pi x radius2. Replace the area, and solve.
