How To Determine The Empirical Formula From 46.25 grams Sample That Contains 14.77 grams Of K 9.06 Of O 22.42 grams Of tin.?
To determine the empirical formula, first calculate the moles of each element present by dividing the given masses by their respective molar masses. Then, divide each mole value by the smallest mole value obtained. Finally, round the resulting ratio to the nearest whole number to determine the subscripts required for the empirical formula. In this case, the empirical formula would be K2O2Sn.
How much does a 100mL round bottom flask weigh?
The weight of a 100mL round bottom flask can vary depending on the material it is made of. A typical 100mL glass round bottom flask weighs approximately 100-150 grams.
If 15 drop of ethanol from a medicine dropper weigh 0.60grams how many drops from the dropper does it take to dispense 1.0mL of ethanol the density of ethanol is 0.80gmL?
First, calculate the weight of 1 drop of ethanol: 0.60 grams / 15 drops = 0.04 grams per drop. To dispense 1.0 mL of ethanol, you will need 1.0 mL / 0.80 g/mL = 1.25 grams. Finally, to find the number of drops, divide the total weight by the weight per drop: 1.25 grams / 0.04 grams per drop = 31.25 drops, round up to 32 drops.

An unknown pesticide is made up of 18.28 percent carbon 0.77 percent hydrogen and 80.95 percent chlorine What is the empirical formula of the pesticide?
I assume that these are weight percents. If so, assume you have 100 g of the substance. Then divide each by the molecular weight to find the number of moles of C, H, & Cl.C: 18.28 g * (1 mole C/12.011 g C) = 1.522 moles CH: 0.77 g * (1 mole H/1.008 g H) = 0.764 moles HCl: 80.95 g * (1 mole Cl/35.453 g Cl) = 2.283 moles ClNext find the ratio of moles of C to H to Cl. To do this divide each by the smallest number of moles from the list, in this case it will be hydrogen.C: 1.522/0.764 = 1.99 (round it to 2)H: 0.764/0.764 = 1.00Cl: 2.283/0.764 = 2.99 (round it to 3)So your empirical formula of the pesticide should be C2HCl3
What is the factor for calculating the weight of a steel round?
To calculate the weight of a steel round, you can use the formula: weight = volume * density. The factor needed would be the density of steel, which is typically around 7850 kg/m³. By knowing the density and the volume of the steel round, you can easily calculate its weight.
How do you calculate the round bar?
To calculate the volume of a round bar, use the formula for the volume of a cylinder: ( V = \pi r^2 h ), where ( r ) is the radius of the bar and ( h ) is its height (or length). First, measure the diameter of the bar, divide it by 2 to find the radius, and then plug the values into the formula. If you need the weight, multiply the volume by the material's density.
Calculate area of a round column?
How to calculate round column volume. +== No formula given so how can the "answer" be useful? The volume of a round column of radius r and height h is that of any cylinder: r^2.pi.h.
Formula to calculate weight of round mild steel?
formula calculation of steel round bar > Area (square metres) of cross section * 7850 = kilograms per metre length. For other lengths, multiply answer by length in metres.
How do i calculate the volume of a round swimming pool?
A round swimming pool is a right circular cylinder, so you can use the formula pi times the radius squared times the height to calculate the volume.
What is the weight of a 24foot aluminum round swimming pool?
To determine the weight of a 24-foot aluminum round swimming pool, we need to calculate the volume of the pool first. The formula to calculate the volume of a cylinder (which the pool resembles) is V = πr^2h, where r is the radius of the pool (half of the diameter) and h is the height (which would be the depth of the pool). Once we have the volume, we can multiply it by the density of aluminum (2.7 g/cm^3) to find the weight in grams. Finally, we can convert the weight from grams to pounds if needed.
What is the formula of calculating weight of a round bar of en1a material if its diameter and length is given?
Density or weight is calculated by mass/volume

How do you calculate the square footage of a round tank?
you use the formula: Pi x radius (half the diameter) squared.
How do you calculate the weight of cast iron?
To calculate the weight of a piece of cast iron, you would need to know its volume and density. The formula to calculate weight is: weight = volume x density. You can find the density of cast iron online or in reference materials.
How do you calculate round column Shuttering area?

How do you calculate circumference of a round tank?
To calculate the circumference of a round tank, use the formula ( C = 2\pi r ), where ( C ) is the circumference and ( r ) is the radius of the tank. Alternatively, if you know the diameter ( d ), you can use the formula ( C = \pi d ). Make sure to use the value of ( \pi ) (approximately 3.14 or 22/7) to get the circumference in the desired units.
