A 1.22g sample of an unknown has a volume of 1.73cm3. What is the density?
They use a number called a mole. This many atoms of an element equals its atomic weight in the periodic table. Molecular weight is the sum of atomic weight. Silver has an atomic weight of 108 grams/mole and Chlorine is 35.4 grams/mole. This makes AgCl 108 + 35.4 = 143.4 grams/mole. The % Chlorine is the atomic weight of Chlorine divided by the molecular weight of AgCl. 1 mole of AgCl would contain 35.4 grams / 143.4 grams = 25% Chlorine by weight. 1.22 grams AgCl would contain (0.25)*(1.22) = 0.30 grams of Cl. To find the Chlorine in the unknown, divide the weight of Chlorine from the experiment by the initial weight of the unknown. 0.30 grams / 0.63 grams = 0.48 = 48% Cl by weight.
How do you determine the atomic mass of chlorine?
Well, the CI atomic number is 17. The atomic mass is 35.4527 amu.There are two stable isotopes of chlorine with relative mass numbers 35 and 37. As the relative abundance of these isotopes are 75% and 25% respectively, the molar mass of chlorine is considered as 35.5 g/mol.
25 mg in liquid measure out to how many tablespoons?
25 mg of liquid =
What element is liquid metal at 25 degrees Celsius?
Mercury (Hg) and Bromine (Br)Liquid at 25 Degrees CelsiusMercury is liquid at 25 degrees Celsius.
What is total residual chlorine?
Total Residual Chlorine (TRC) is the total of free available residual chlorine and combined (bound) residual chlorine. The amount of measurable chlorine remaining after treating water with chlorine i.e. amount of chlorine left in water after the chlorine demand has been satisfied
Is the element chlorine a solid liquid or gas at room temp 298 K?
Chlorine is a gas at room temperature and pressure. Its melting point is −101.5 °C while its boiling point is −34.04 °C. So at 25 °C, it would be in the gaseous state.
How many kilograms of chlorine are in 25 kg of CF2Cl2?
10kg
What metal turns to liquid at 25 degrees Celsius?
Mercury turns to a liquid at 25 degrees Celsius.
25 mg of liquid medicine is how many ml?
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
Is vinegar a liquid or a solid liquid?
Vinegar is a liquid at temperatures around 25 degrees celcius.
What is the volume of a liquid used to determine density?
Density is a calculated value, it is not determined a from any specific volume. It is usually reported as gm/cm3. Assume you have 25 ml of a liquid. A ml equals 1 cm3. The liquid is weighed and found to have a weight of 25 gm. There are fine points about whether this is a weight of 25 gm or mass of 25 gm, but assume this was weighed on an equal arm balance so the terms are equivalent. Most commonly density is the number of gms of material in 1 cm3 (gm/cm3). Since 25 cm3 weighs 25 gm the density is 25gm/25 cm3 or 1 gm/cm3. Some industrial users may use kg/m3. For gases the process is similar, but the answer is usually adjusted to some standard of temperature and pressure.
What state is chlorine in at 0 degrees Celsius?
Chlorine is a solid at 0 degrees celsius because it's also a solid at 25 degrees celsius.
