What is the mole ratio of the mercury to oxygen in the sample?
To determine the mole ratio of mercury to oxygen in a sample, you need to know the chemical formula of the compound containing these elements. For example, in mercuric oxide (HgO), the mole ratio of mercury to oxygen is 1:1. If the sample is a different compound, the ratio will vary accordingly based on its chemical formula. Without specific information about the compound, the mole ratio cannot be accurately defined.
Is magnesium an element or compound?
Magnesium is an element.it is a compound as it is made up of two elements
Is the number of atoms in a sample directly related to the mass of that sample?
If the chemical composition of the sample is known, then the answer is yes. However, equal masses of platinum and magnesium, for example, contain quite different numbers of atoms, because the atomic mass of platinum is much higher than that of magnesium.
Is iron filings and sand a compound or an element?
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).
How ir spectrum compound recorded?
An IR spectrum of a compound is recorded by passing infrared radiation through a sample of the compound and measuring the absorption of different wavelengths by the sample. The resulting spectrum displays peaks and troughs corresponding to different functional groups present in the compound, which provides information about its structure and composition.
Is the original water liquid sample a compound an element a heterogeneous mixture or a homogeneous mixture?
Water (H2O) is a chemical compound.
What is a sample of a matter either single element or a single compound that has a definite chemical and physical properties?
a pure substance. :)
How to find the percent by mass of a compound in a given sample?
To find the percent by mass of a compound in a given sample, you need to divide the mass of the compound by the total mass of the sample and then multiply by 100. This will give you the percentage of the compound in the sample.
What is a sample of matter either a single element or a single compound?
a pure substance! ;)
Is a sample of matter that contains more than one type of atom chemically bonded together in a set proportion?
This is a chemical compound.
How many molecules are in sample 57.45 CF2Cl2?
To calculate the number of molecules in a sample, you need to know the mass of the sample and the molar mass of the compound. Then you can use Avogadro's number (6.022 x 10^23) to convert from grams to molecules.
Who said Any sample of a chemical compound will contain the same elements in the same proportions?
This is the law of definite proportions: Joseph Proust, 1806.
Is magnesium an element or compound?

How many moles in NaCHO3?
A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
Is tungsten a compound mixture or element?
Tungsten carbide is a metallic chemical compound. Unlike steel, it is not a mixture or alloy. The chemical formula for tungsten carbide is WC, indicating that the number of atoms of tungsten (W) in a sample of tungsten carbide is equal to the number of number of atoms of carbon (C) in that sample. Because each atom of tungsten weighs about 15.3 times as much as each atom of carbon, almost 94% of the mass of a sample of tungsten carbide is represented by tungsten atoms. Although tungsten carbide is not itself a mixture, it is often mixed (alloyed) with other metals such as nickel or cobalt.
How many molecules are contained in a 5.00 g sample of dimethylmercury?
To determine the number of molecules in a sample, you need to know the molar mass of the compound. For dimethylmercury, the molar mass is approximately 230.6 g/mol. You can then use the formula n = m/M, where n is the number of moles, m is the mass of the sample, and M is the molar mass, to calculate the number of molecules in the sample.
Is the number of atoms in a sample directly related to the mass of that sample?
If the chemical composition of the sample is known, then the answer is yes. However, equal masses of platinum and magnesium, for example, contain quite different numbers of atoms, because the atomic mass of platinum is much higher than that of magnesium.
